Available in PDF, EPUB and Kindle. Book excerpt: The chemistry of transition metal chalcogenide polynuclear clusters is a rapidly expanding area. The increasing interest is due to the search for structural models and precursors of extended inorganic solids with novel electronic, magnetic and optical properties. Our interest for the synthesis of a variety of transition - etal clusters is due to their use as a model and precursors for materials and catalyst. Synthesis and study of a variety of ligand substituted iron carbonyl cluster has been carried out to understand the reactivity features and structural variety. The main focus has been on the transition metal clusters containing chalcogens which act as bridges between different metal fragments and are helpful in cluster growth reactions and maintains the cluster integrity. A synthetic strategy has been developed to prepare a mixed metal cluster when a dichloromethane solution of [Fe3Y2(CO)6], Y=S, Se, Te and ML4 (M=Pd, L=PPh3) was reacted at room temperature in presence of trimethylamine-N-oxide. Substitution reaction of carbonyl groups by triphenylphosphine and bis(diphenylphosphino)methane ligands results in the formation of different types of trinuclear clusters. Homo metallic cluster as well mixed metal clusters with phosphine ligands has been synthesized by a room temperature reaction and characterized by FTIR, proton and 31P NMR spectroscopy. Some of the transition metal cluster contains chelating phosphine ligands which stabilizes the cluster integrity.

Geoffroy and published by . This book was released on 1977 with total page 39 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transition metal cluster complexes have become a very important class of compounds, principally because of their potential in catalysis. Clusters have been shown to behave as catalysts in their own right and they hold considerable promise for serving as models for catalytic surfaces. Clusters comprised of two or more different transition metals in the cluster framework are particularly interesting in this regard because of possible bimetallic effects. Further, mixed-metal clusters have non-equivalent bonding sites. As such they are ideally suited for modeling studies which employ variable temperature NMR to follow the movements of substrates over their surfaces. One of the problems which has hampered studies of mixed-metal clusters is their relative lack of availability. Only a very few isostructural series have been achieved, and general synthetic methods for mixed-metal clusters are lacking. Carbonylmetalates have been widely used as synthetic reagents in cluster chemistry and several of the reported reactions appear to be adaptable to design. This is particularly true of the reactions of Knight and Mays who prepared a series of Group 7 - Group 8 tetrameric mixed-metal clusters through the addition of a carbonylmetalate to a closed M3(CO)12 trimer.

Book excerpt: With an enormous velocity, olefin polymerization has expanded to one of the most significant fields in polymers since the first industrial use about 50 years ago. In 2005, 100 million tons of polyolefins were produced - the biggest part was catalyzed by metallorganic compounds. The Hamburg Macromolecular Symposium 2005 with the title "Olefin Polymerization" involved topics such as new catalysts and cocatalysts, kinetics, mechanism and polymer reaction engineering, synthesis of special polymers, and characterization of polyolefins. The conference combined scientists from different disciplines to discuss latest research results of polymers and to offer each other the possibility of cooperation. This is reflected in this volume, which contains invited lectures and selected posters presented at the symposium.

Download or read book Cluster Chemistry written by Guillermo Gonzalez-Moraga and published by Springer Science & Business Media. This book was released on 2013-11-09 with total page 310 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cluster chemistry is one of the recent, exciting areas of Inorganic Chemistry. The occurence of molecular clusters, like fullerene C60, constitutes a fundamental feature midway between the chemistry of isolated chemical compounds and that of the elements. Main features of the Cluster Chemistry of both main group and transition metal elements are treated in this book. The author highlights aspects releated to the synthesis, the structure, the special bonding and the reactivity of these species. The book is written as a textbook for senior undergraduate and postgraduate students. References in tables andillustrations permit the reader to reach relevant original information. Professor Gonzalez-Moraga fills a demand for a publication appropriate for dissemination and specially for teaching this exciting subject. From the Contents: Current Concepts in Modern Chemistry - Transition Metal Cluster Chemistry - Main Group-Transition Metal Mixed Clusters - Cluster Compounds of the Main Group Elements - Synthetic Analogues of the Active Sites of Iron-Sulfur Proteins.

This book was released on 2013-11-11 with total page 335 pages. Available in PDF, EPUB and Kindle. Book excerpt: Molecular clusters, in the broad sense that the term is commonly understood, today comprise an enormous class of species extending into virtually every important area of chemistry: "naked" metal clusters, transition metal carbonyl clusters, hydrocarbon cages such as cubane (C H ) and dodecahedrane (C H ), 8 8 20 20 organometallic cluster complexes, enzymes containing Fe S or MoFe S 4 4 3 4 cores, high polymers based on carborane units, and, of course, the many kinds of polyhedral borane species. So large is the area spanned by these diverse classes that any attempt to deal with them comprehensively in one volume would, to say the least, be ambitious-and also premature. We are presently at a stage where intriguing relationships between the various cluster families are becoming apparent (particularly in terms of bonding descriptions), and despite large dif ferences in their chemistry an underlying unity is gradually developing in the field. For example, structural changes occurring in Fe S cores as electrons are 4 4 pumped in and out, in some measure resemble those observed in boranes and carboranes. The cleavage of alkynes via incorporation into carborane cages and subsequent cage rearrangement, a sequence familiar to boron chemists, is a thermodynamically favored process which may be related to the behavior of unsaturated hydrocarbons on metal surfaces; analogies of this sort have drawn attention from theorists and experimentalists.
