This book was released on 2017 with total page 296 pages. Available in PDF, EPUB and Kindle. Book excerpt: Investigations of the oxidatively-resistant hexacarboxamide cryptand, mBDCA-5t-H6, to support mono-, bi-, and trimetallic complexes are presented. Selective single metal ion insertion into the cryptand was achieved to generate the mono-Co(II) and Zn(II) complexes that contain proximal hydrogen-bonding networks enforced by the carboxamide N–H groups of the pre-organized second-coordination sphere. The cobalt(II) complex serves as a selective colorimetric turn-on fluoride sensor and represents a unique example of a transition-metal based fluoride sensor where fluoride binding takes place directly at the transition metal. The binding of fluoride is synergistic involving hydrogen-bond donors from the second-coordination sphere together with metal(II) ion coordination. Isolation of the mono-metallic Co and Zn complexes allowed for the preparation of their transition and main group metal heterobimetallic variants. Hetero- and homobimetallic complexes of cobalt(II) and zinc(II) are presented, and the reactivity of the homobimetallic complexes with O2, O−2 , and H2O2 is discussed. The cryptand was also explored as a supporting ligand for cofacially arranged divalent group 14 ions (Ge, Sn, Pb). Reaction of the di-tin(II) complex with elemental sulfur or selenium generates di-tin polychalcogenide complexes containing [mu]–E and bridging [mu]– E5 ligands (E = Se, S), where the sulfur-containing product acts reversibly as a source of S3 ∙− in DMF solution. The di-tin(II) complex also serves as a bidentate ligand for the preparation of trimetallic Sn2/M complexes (M = Ag(I), Au(I), Pd(0)). Reactivity studies of the Sn2/Pd(0) complex with substrates including CS2, S8, and 1AdC≡P are described. Terminal titanyl complexes supported by oxidatively-resistant tri- and tetrametaphosphates were prepared as molecular models of heterogeneous oxidation catalysts. These complexes react with hydrogen peroxide to produce the corresponding peroxotitanium( IV) metaphosphates, and represent rare examples of titanium oxo and peroxo systems supported by an all-oxygen ligand environment.
Download or read book Comprehensive Organometallic Chemistry II Volume 7 written by D.F. Schriver and published by Elsevier. This book was released on 2002-09-10 with total page 1071 pages. Available in PDF, EPUB and Kindle. Book excerpt: The section devoted to iron in this volume reflects the tremendous progress in the area. Specifically cluster chemistry, ligand transformations and detailed structural results are more prominent in COMC II. The organic chemistry of ruthenium and osmium is an area which has burgeoned during the period since the publication of COMC. This is especially true for the cluster chemistry of these elements, which have provided most of the advances in this important field. Consequently, this volume will include an update (1981-1993) of the chemistry of mono- and bi-nuclear complexes of ruthenium and osmium, with a rather more extensive treatment of tri- and tetra-nuclear complexes. This is because many of the early results in ruthenium and osmium cluster chemistry described in COMC are now much better understood and can thus be placed in a more general context. In the case of complexes containing clusters with five or more metal atoms, the coverage is essentially complete, again because this chemistry has developed during the 1980s.

Available in PDF, EPUB and Kindle. Book excerpt: The major aim of this work has been to extend the range of known molybdenum and tungsten complexes which have some relevance to nitrogenase. Many of these compounds may also be of import to the hydrodesulphurization process. Chapter 1 contains a brief introduction to the chemistry of sulphur which is pertinent to the remainder of this work. Chapters 2 and 3 are concerned with the reaction of the complex {M02&gS2) with various nitrogen-, oxygen- and sulphur-containing ligands, and the characterization of these products by spectroscopic and analytical methods. Chapter 4 details the reaction of some of these products with H+ and compares them to known Mo-H and Mo-S-H species. Chapter 5 explains the unexpected formation of the lattice adduct [WSC14].S8 from W(CO)6 and S2Cl2, and compares its crystal structure and reactions with the known compound [WSCl4J. Chapters 6 and 7 describe the preparation, characterization and reactions of the complexes [MoH(SAr)3(PMe2Ph)2l and [MoH(SAr)3(PMePh2) ] (SAr - tipt or tmt). The crystal structures of the complexes [MoH(tipt)3 (PMe2Ph)2 ] and [Mo(tipt)2(00)2(PMe2Ph)2] are described, and many of the reactions of these compounds are compared with those of the analogous tungsten compounds lWH(SAr)3(PMe2Ph)2] (SAr - tipt or tmt). In Chapter 8 a general discussion and summary of the preceding Chapters is given, together with some suggestions for further work.iii.

Book excerpt: Present book provides an insight to the synthesis, characterization and structural analysis of compounds containing nitrogen and sulfur containing chelating agents. Keeping in mind the biological, medicinal, industrial and chelating importance of sulfur (alone) and nitrogen containing donor ligands, two important chelating agents, viz Potassium-2-trithiocarbonatoethyl xanthate (PTEX) and 2-amino-4-benzamido thiosemicarbazide (ABTSC) have been discussed in details w.r.t. their synthesis, characterization and metals complexes. All the possible techniques have been dealt in order to elucidate the structures of the complexes generated.
