Download or read book Structural and Biological Applications of Schiff Base Metal Complexes written by Pallavi Jain and published by CRC Press. This book was released on 2023-05-31 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: Coordination compounds have been well-known for their wide variety of applications for over a century, as well as enhancing the researcher’s interest and concern in evaluating their action mechanism. It is certainly one of the most intensely discussed research topics. Coordination compounds involve different metal-ion-ligand phenomenon. The involved metal ions play a significant role in structural association and functioning of several processes in the genetic and metabolism system. In recent years, Schiff base ligands have gained significant interest and received a keen interest of many researchers. Schiff’s base ligands have been recognized to hold a wide variety of biological and medicinal activities due to the presence of donor atoms. They have proved exceptional pharmalogical actions such as antimicrobial, anti-tuberclosis, antiplatelet, antidiabetic, antiarthritis, antioxidant, anti-inflammatory, anticancer, antiviral, antimalarial, and analgesic. These biologically active Schiff base ligands have also been shown to inhibit enzyme mobilization and, when bound to a metal ion, exhibit enhanced biological activity, making them useful in a number of fields. As a result, metal complexes of Schiff base ligands are gaining popularity due to their unique properties and functionalities. Schiff base complex-based research for educational and industrial purposes is booming, and the number of publications is gradually increasing. Despite these interests, there is currently no detailed book on Schiff base metal complexes that covers the structures, biological activities, and other non-biological perspectives. This book delves into the structures of Schiff base metal complexes, which are critical in assessing the biological viability of any complex. It also highlights their biological significance in pharma and drug discovery like antibacterial, antifungal, anticancer, anti-inflammatory, anti-arthritis, anti-diabetic, antioxidants, anti-proliferative, antitumor, anticancer, antiviral. The fundamentals of metal complexes are described, as well as an up-to-date outline of developments in synthesis, characterization methods, properties- chemical, thermal, optical, structural, and applications. This book also discusses the other applications of Schiff base metal complexes: as sensor (luminescent, electrochemical, and biosensor), as pigments in dying and paint industries, as photocatalyst to improve the degradation rate. Features : This book would be useful for academia, researchers and engineers working in the area of Schiff base and their metal complexes. This book will give an in-depth account of the properties of Schiff base and their metal complexes. This book will discuss the details of synthesis methods for Schiff base and their metal complexes. This book will cover emerging trends in the use of Schiff base metal complexes in the industry. This book will provide an overview of the wider biological applications of Schiff base metal complexes

Available in PDF, EPUB and Kindle. Book excerpt: Direct Synthesis of Metal Complexes provides in-depth coverage of the direct synthesis of coordination and organometallic compounds. The work is primarily organized by methods, but also covers highly relevant complexes, such as metal-polymer coordination compounds. This updated reference discusses recent developments in cryosynthesis, electrosynthesis, and tribosynthesis (popular as it doesn't require organic solvents), with special attention paid to 'greener' methodologies and approaches. Additionally, the book describes physical methods of zero-valent metal interaction with organic matter, including sputtering, ultrasonic treatment and synthesis in ionic liquids. The book presents completely new content as a follow-up to the 1999 Elsevier Science publication Direct Synthesis of Coordination and Organometallic Compounds that was edited by Dr. Garnovskii and Dr. Kharisov. - Covers current methods and techniques of metal interactions with organic media leading to metal chelates, adducts, di- and polymetallic complexes, metal-containing macrocycles, supported coordination compounds (i.e., metal complexes on carbon nanotubes), and more - Describes reactivities of distinct forms of elemental metals (powders, sheets, nanoparticles (including a host of less-common metal nanostructures) with organic phase (liquid, solid and gaseous) and water - Includes experimental procedures, with examples of direct synthesis, at the end of each chapter

Download or read book Ligand Field Theory and Its Applications written by Brian N. Figgis and published by Wiley-VCH. This book was released on 2000 with total page 384 pages. Available in PDF, EPUB and Kindle. Book excerpt: A complete, up-to-date treatment of ligand field theory and its applications Ligand Field Theory and Its Applications presents an up-to-date account of ligand field theory, the model currently used to describe the metal-ligand interactions in transition metal compounds, and the way it is used to interpret the physical properties of the complexes. It examines the traditional electrostatic crystal field model, still widely used by physicists, as well as covalent approaches such as the angular overlap model, which interprets the metal ligand interactions using parameters relating directly to chemical behavior. Written by internationally recognized experts in the field, this book provides a comparison between ligand field theory and more sophisticated treatments as well as an account of the methods used to calculate the energy levels in compounds of the transition metals. It also covers physical properties such as stereochemistry, light absorption, and magnetic behavior. An emphasis on the interpretation of experimental results broadens the book's field of interest beyond transition metal chemistry into the many other areas where these metal ions play an important role. As clear and accessible as Brian Figgis's 1966 classic Introduction to Ligand Fields, this new book provides inorganic and bioinorganic chemists as well as physical chemists, chemical physicists, and spectroscopists with a much-needed overview of the many significant changes that have taken place in ligand field theory over the past 30 years.

This book was released on 2012-12-06 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the oil embargo, in the winter 1973174, parts of Western Europe present ed an almost war-like aspect on Saturdays and Sundays: no traffic on the high ways, no crowds at ski resorts and other weekend entertainment places, no gaso line at the pumps. Living and teaching then in that part of the world, and discussing the situa tion with our students, we came to the conclusion that it would be timely to col lect the fine chemistry already known at the time in the field of conversion of coal to gasoline and other chemicals, and by this way help to draw the attention to this important alternative to crude oil. The idea of this book was born. The energy shock of the early seventies has been healthy and of great conse quences in chemistry. Large amounts of research money have been put to work since, and our knowledge of the possibilities and limitations of coal-based chemistry has increased enormously. During several years it appeared inap propriate to write a monograph about a topic which was in the midst of such an impetuous development. Nevertheless, we collected, and critically selected, the upcoming work as it appeared in the literature, and also tried to provide some modest input ourselves. Now, ten years later, the situation seems to be settled to a certain degree.

Book excerpt: In the current era of incessant developing needs for the betterment and ease in living style for humans, technology is seeking upgraded, well structured materials for utilization in various fields of human-wellness such as medication, energy, environment protection and cleaning, food security etc. In the same direction, chemists are doing very well at synthesizing compounds and materials from different groups of chemicals. Among them, coordination compounds also play a key role in serving humanity as these compounds have a wide range of applications in health care from antimicrobial to anticancer, bioengineering, bio-mimetic models, catalysis, photosensitized materials etc. Along with development of stable coordination compounds, their extensive structural studies are also in the main line of work for researchers. Twenty-nine authors from different countries have contributed their scientific views and work in magnifying the importance and scope of coordination compounds in the present book entitled “Stability and Applications of Coordination Compounds”. I hope that the book will achieve its target of supplementing the community of researchers and readers working in the field of coordination chemistry.

Download or read book Low Frequency Vibrations of Inorganic and Coordination Compounds written by John R. Ferraro and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the course of far-infrared investigations of inorganic and coordina tion compounds at Argonne National Laboratory in the years 1962-1966, it became apparent that no suitable book existed which correlated and dis cussed the important vibrations occurring in this region for these molecules. Early in 1967 the initial steps were taken to write such a book. Then, in 1968, an excellent text by Professor David M. Adams entitled Metal-Ligand and Related Vibrations was published. At this point serious consideration was given to discontinuing work on this book. However, upon examination of Adams' book, it became clear that the references covered only the period to 1966. This field of research is accelerating so tremendously, and the period 1966-1969 has seen so many new studies, that upon reconsideration it was decided to continue writing this text. The references in this book, particularly in the last several chapters, include many papers published in 1969. However, the proliferation of the far-infrared literature has made it impossible to present all the published material that has any bearing on the subject. Many titles do not pertain primarily to the far-infrared region as such, and some of this research has been omitted for this reason. Organometallic compounds have been neglected since the author feels that adequate reviews of that subject are available. Other studies may be missing simply because, owing to space limitations, only the more important researches could be considered. Of course, "importance" may, in this case, reflect the author's interest and prejudices.
