Download or read book The Chemistry of Ruthenium written by E.A. Seddon and published by Elsevier. This book was released on 2013-10-22 with total page 1414 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chemistry of Ruthenium is concerned with the chemistry of ruthenium, with emphasis on synthesis and structure. The discussion spans a wide range of fields, from coordination chemistry and organometallic chemistry to structural chemistry (of both molecular and extended lattices), electrochemistry and photochemistry, as well as kinetics and spectroscopy. Comprised of 15 chapters, this book begins with an introduction to the discovery and early history of ruthenium, along with its extraction and purification, isotopes, physical and chemical properties, and applications. The discussion then turns to the concept of oxidation state and a scheme for systematizing descriptive inorganic chemistry together with its applicability to ruthenium chemistry. Subsequent chapters focus on the chemistry of ruthenium(VIII), ruthenium(VII), ruthenium(VI), ruthenium(V), ruthenium(IV), ruthenium(III), ruthenium(II), ruthenium(I), and ruthenium(0). The book also considers ruthenium carbonyl clusters and nitrosyls before concluding with a review of the photophysics and photochemistry of tris(diimine)ruthenium(II) complexes. This monograph will be useful to students, practitioners, and researchers in the field of inorganic chemistry, as well as those who are interested in the chemistry of ruthenium.
Download or read book Ruthenium Chemistry written by Ajay Kumar Mishra and published by CRC Press. This book was released on 2018-01-17 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book will describe Ruthenium complexes as chemotherapeutic agent specifically at tumor site. It has been the most challenging task in the area of cancer therapy. Nanoparticles are now emerging as the most effective alternative to traditional chemotherapeutic approach. Nanoparticles have been shown to be useful in this respect. However, in view of organ system complicacies, instead of using nanoparticles as a delivery tool, it will be more appropriate to synthesize a drug of nanoparticle size that can use blood transport mechanism to reach the tumor site and regress cancer. Due to less toxicity and effective bio-distribution, ruthenium (Ru) complexes are of much current interest. Additionally, lumiscent Ru-complexes can be synthesized in nanoparticle size and can be directly traced at tissue level. The book will contain the synthesis, characterization, and applications of various Ruthenium complexes as chemotherapeutic agents. The book will also cover the introduction to chemotherapy, classification of Ru- complexes with respect to their oxidation states and geometry, Ruthenium complexes of nano size: shape and binding- selectivity, binding of ruthenium complexes with DNA, DNA cleavage studies and cytotoxicity. The present book will be more beneficial to researchers, scientists and biomedical. Current book will empower specially to younger generation to create a new world of ruthenium chemistry in material science as well as in medicines. This book will be also beneficial to national/international research laboratories, and academia with interest in the area of coordination chemistry more especially to the Ruthenium compounds and its applications.

This book was released on 2017 with total page 212 pages. Available in PDF, EPUB and Kindle. Book excerpt: Global concern about the long-term sustainability and environmental impact of burning fossil fuels has prompted widespread research on alternative fuels. Hydrogen is attractive as a chemical fuel because it is carbon-free and therefore its exothermic reaction with oxygen does not generate CO2 as a byproduct. Large scale implementation of hydrogen, however, depends on efficient and clean production of hydrogen from non-fossil sources. Splitting water with sunlight is often considered the "Holy Grail" of a sustainable hydrogen economy, however the greatest challenge towards achieving this goal is in lowering the high kinetic barrier of the water oxidation half reaction. With the right electronics and geometry of coordinated ligands, transition metals can effectively mediate the loss of 4 e- / 4 H+ required to oxidize water. This dissertation details the syntheses, characterization, and reactivities of three novel catalytic systems containing multi-functional ligands that appear to have a marked effect on catalysis. Chapter 2 details the synthesis and reactivity of novel ruthenium complexes bearing 2,2'-bipyridine ligands with various pyrazolate groups in the 6,6'-positions. The structures of these complexes were characterized by NMR spectroscopy and x-ray crystallography and for one of the complexes, the unique solvatochromic and acid-base properties involving the uncoordinated nitrogen atoms of the ligand were investigated by non-aqueous and aqueous UV-visible spectroscopy and electrochemistry. Rapid O2 evolution was witnessed under acidic conditions in the presence of CeIV. While the apparent rates (between 3 and 4 s-1) are in the upper range of rates observed for ruthenium-based molecular catalysts, lag periods observed for 1-1.5 min prior to O2 production may be indications of slow catalyst dissolution or activation, or of catalyst modification. Alternatively, CeIV may have a non-innocent role during catalysis by interaction with the uncoordinated nitrogen. Chapter 3 details the synthesis and catalysis-relevant properties of two novel ruthenium complexes, [Ru(2,2'-bipyridine-6,6'-diphosphonato)(pic)2] (pic=4-picoline) and [Ru(6,6'-diisopropyl-2,2'-bipyridine-6,6'-diphosphonato)(pic)2]. These complexes are the first examples of water oxidation catalysts deliberately bearing phosphonate groups positioned to serve as metal-bound ligands. They have been characterized by NMR spectroscopy, elemental analyses, x-ray crystallography, cyclic voltammetry, and UV-visible spectroscopy. From electrochemical data, we have discovered that charge states of P-OH / P-OR groups have a significant influence on redox and catalytic properties, features that are absent in much more commonly studied carboxylate analogs. Chapter 4 details the synthesis and reactivity of a series of ruthenium complexes bearing novel 2,2'-biimidazole-4,4'-phosphonate ligands. Surprisingly, the new ligands did not participate in the intended tetradentate coordination, but instead bidentate N,N'-coordination, placing the phosphonate groups in the secondary coordination sphere to engage in hydrogen bonding interactions with two aquo ligands. The presented complexes have been characterized by NMR spectroscopy, x-ray crystallography, and cyclic voltammetry. Qualitative and quantitative oxygen evolution studies (from cyclic voltammetry and addition of excess CeIV, respectively) have shown a dramatic improvement in catalytic rates compared to those of previously reported Ru diaquo complexes. Our working hypothesis to explain the superior catalytic activity includes involvement of the phosphonates in the secondary coordination sphere potentially as basic proton-relaying functionalities.

Download or read book Inorganometallic Chemistry written by Thomas P. Fehlner and published by Springer Science & Business Media. This book was released on 2013-11-22 with total page 409 pages. Available in PDF, EPUB and Kindle. Book excerpt: There is a certain fascination associated with words. The manipulation of strings of symbols according to mutually accepted rules allows a language to express history as well as to formulate challenges for the future. But language changes as old words are used in a new context and new words are created to describe changing situations. How many words has the computer revolution alone added to languages? "Inorganometallic" is a word you probably have never encountered before. It is one created from old words to express a new presence. A strange sounding word, it is also a term fraught with internal contradiction caused by the accepted meanings of its constituent parts. "In organic" is the name of a discipline of chemistry while "metallic" refers to a set of elements constituting a subsection of that discipline. Why then this Carrollian approach to entitling a set of serious academic papers? Organic, the acknowledged doyenne of chemistry, is distinguished from her brother, inorganic, by the prefix "in," i. e. , he gets everything not organic. Organometallic refers to compounds with carbon-metal bonds. It is simple! Inorganometallic is everything else, i. e. , compounds with noncarbon-metal element bonds. But why a new term? Is not inorganic sufficient? By virtue of training, limited time, resources, co-workers, and so on, chemists tend to work on a specific element class, on a particular compound type, or in a particular phase. Thus, one finds element-oriented chemists (e. g.
