This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Nitrogen based monodentate and bidentate chelating ligands have captured a significant interest due to their ability to coordinate to a wide variety of elements. The â-diketimine, â-ketoiminato, formamidine, pyridineselenolate, and pyrazinecarboxamide ligands have all been employed in this study to further investigate the coordination preferences among main group and transition metals. Steric and electronic properties of these ligands can easily be altered by manipulating the substituents attached, thus leading to predictable structures with potential for many useful and significant applications. Investigations have shown that temperature, solvent, and metal halide employed are all key factors in the reaction outcomes. All of the complexes obtained throughout these studies have been characterized by X-ray crystallography along with other spectroscopic techniques, including NMR, IR, UV/Vis, and M/S. â-diketiminato ligands, [{N(R)C(Me)}2C(H)] where R = Dipp, Mes, commonly referred to as nacnac, have played an important role in the synthesis of novel pnictogenium complexes. Results show that through manipulation of the halide precursor, reaction stoichiometry, and the R substituent on the nacnac both N, N'- and N, C'-metal chelated complexes can be achieved. Additionally, â-ketiminato ligands, [RN(H)(C(Me))2C(Me)=O] where R = Dipp, and [RN(H)C(Me)CHC(Me)=O] where R = C2H4NEt2, have been studied. Both ligands were investigated with a range of d and p block metal halides and alkyls in order to compare and contrast the bulky, flexible, and even multi-dentate nature of each ligand. The preferred metal geometry remains constant for products with either ligand, but the steric protection offered by the individual ligands governs the nuclearity of the products, ranging from tetrameric cages to simple adducts. The formamidinate ligand, [RN(H)C(H)NR] where R = Dipp, was employed in synthesizing several aluminum and zinc complexes. In addition to their numerous applications as cata.

Book excerpt: To meet the search for new therapeutic compounds this book summarises the research on biologically active organic molecules (chapters 1, 2 and 3), metal complexes with biological activity (chapter 4), and shows the possibilities for co-ordination chemistry in the planning of metal complexes with interesting properties for application (chapters 5, 6, 7, 8, and 9). It should be remembered that in the design of a new potentially active metallodrug, beyond the nature of the metal, the choice of appropriate ligands which affect the thermodynamic and kinetic stability, as well as the solubility and lipophilicity of the complexes is of paramount importance. The information contained in the book concerns: 1) the interactions involving the members of the Nuclear Receptor superfamily and their ligands; 2) the role of chemokine ligands and their receptors in normal and disease processes, and the emerging therapeutic approaches of using chemokine antagonists for appropriately targeted therapy; 3) the inhibition of alkaline phosphatases by calix[4]arenes functionalysed at the macrocyclic upper rim by one or two methylenebisphosphonic acid fragments; 4) the main biological applications, enzyme modelling and antiproliferative and antimicrobial activity of such scorpionate-type complexes, which are classified by ligand and also by transition metal; 5) the silver(I) discrete and polymeric coordination compounds bearing 1,3,5-triaza-7-phosphaadamantane or its derivatives towards engineering functional silver-organic frameworks (MOFs); 6) arylhydrazones of methylene active nitriles and their use as starting materials for the generation of new organic and coordination compounds; 7) amidophosphate ligands as promising sensitisers of lanthanide ions emission; 8) N-acetylsalicylhydrazidate as a versatile ligand for the synthesis of higher nuclearity metal complexes, which are illustrated herein along with their applications; 9) the chemistry and some applications of formazans which can be used for the simultaneous selective determination of several metal cations. All chapters were compiled by renowned scientists, providing both beginners in the field and advanced researchers with comprehensive information on the subject.

This book was released on 2013 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Chapter 5 describes two multidentate, L3X type ligands, which feature [CN3] and [CNO2] donors, namely tris(2 pyridylseleno)methane, [Tpsem]H, and bis(2-pyridonyl)(pyridin-2-yloxy)methane, [O-poBpom]H. They have been synthesized, characterized, and employed in the synthesis of zinc and cadmium complexes. Chapter 6 describes the synthesis and structural characterization of a new [Tp] ligand featuring an allyl substituent on the central boron atom, namely [allylTpBut]Li is reported. The compound reacts steadily with CH3CH2SH under 350 nm UV light via a thiol-ene click reaction. The resulting [CH3CH2S(CH2)3TpBut]Li complex can further react with metal halide. For example, the reaction of [CH3CH2S(CH2)3TpBut]Li with ZnI2 produced [CH3CH2S(CH2)3TpBut]ZnI at room temperature. This study provides a simple model on the immobilization of [Tp] metal complexes to the polymer chains with -SH terminals.

This book was released on 2019 with total page 191 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over recent years a great deal of interest has developed in new transition metal complexes of Schiff base ligand. The preparation of new ligand is the most important step in the development of metal complexes that exhibit unique properties and novel reactivity. The electron donor and electron acceptor properties of the ligand, the structural function groups and the position of the ligand in the coordination sphere, together with the reactivity of coordination compounds may be the factor for different studies. The synthesis and structural investigations of Schiff bases and their metal complexes are a considerable center of attention because of their potentially beneficial pharmacological properties and a wide variation in their mode of bonding. Metal coordination complexes have a wide variety of technological and industrial application, ranging from catalysis to anticancer drugs. In these compounds the metal atom itself may have a number of roles, based on its coordination geometry, oxidation state, and magnetic electronic and photochemical behaviors. This study presents the synthesis, characterization, and structural studies of different series of Copper and Uranium complexes of salicylaldehyde Schiff base derivatives with various organic amine compounds. The Schiff bases act as neutral and bidentate ligands, which can attach the metal through the azomethine nitrogen and furfural oxygens. These Schiff bases are prepared by iii reacting salicylaldehyde with various organic amines. In the case of most complexation reactions, highly colored precipitates were formed immediately. The complexes were found to have composition ML2 and M2L2, where M is the metal and L the organic ligand. This implies "mononuclear" structures with one metal + 2 ligands, and "binuclear" where the ligands hold two metal atoms in close proximity. The interesting molecular and crystal structural features of the Schiff base ligand called E-2-((benzo[d]thiazol-2-ylimino)methyl)phenol and its Cu(II) complex are presented in Chapter 2. Further investigations on the coordination chemistry of the Schiff base ligands are made by reacting these ligands with copper and uranium, described in Chapter 3. Another series of dicopper(II) complexes and diuranium complex of the Schiff base ligands, containing azomethine nitrogen and furfural oxygen donor group are investigated to evaluate the role of alkoxo bridge on the structures. Making the compounds with two uranium atoms leads to very high molecular weight, as a path to the highest molecular weight liquid crystal. This lays the pathway to future work for making those crystals. These dinuclear complexes are presented in chapter 4. The objective of the present study is to investigate the coordination chemistry of these ligands with Copper and Uranium. For the ligands this was done by a combination of nuclear magnetic resonance spectroscopy, infrared spectroscopy, ultraviolet-visible spectroscopy and single X-ray crystallography. The metal complexes were analyzed by the same techniques, except that in the case of uranium, all efforts to obtain single crystal for X-ray crystallography proved unsuccessful, so the molecular structure had to be ascertained from the other techniques.
