Book Description
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.

Book Description
Chelation Therapy in the Treatment of Metal Intoxication presents a practical guide to the use of chelation therapy, from its basic chemistry, to available chelating antidotes, and the application of chelating agents. Several metals have long been known to be toxic to humans, and continue to pose great difficulty to treat. These challenges pose particular problems in industrial settings, with lead smelting known to be associated with hemopoietic alterations and paralyses, and the inhalation of mercury vapor in mercury mining being extremely detrimental to the central nervous system. Clinical experience has demonstrated that acute and chronic human intoxications with a range of metals can be treated efficiently by administration of chelating agents. Chelation Therapy in the Treatment of Metal Intoxication describes the chemical and biological principles of chelation in the treatment of these toxic metal compounds, including new chelators such as meso-2,3-dimercaptosuccinic acid (DMSA) and D,L-2,3-dimercapto-1-propanesulfonic acid (DMPS). Presents all the current findings on the potential for chelation as a therapy for metal intoxication Presents practical guidelines for selecting the most appropriate chelating agent Includes coverage on radionuclide exposure and metal storage diseases Describes the chemical and biological principles of chelation in the treatment of toxic metal compounds

Book Description
This book deals with the chemistry of polymeric metal chelates. The main results and the production and chemical structure of polymers with chelate units as well as the specificity of metal complex binding of different structure are presented here. This book also reveals the transformations which components undergo in the course of chelation. Special attention is paid not only to synthetic but also to natural (including living) systems. The usage of polymeric metal chelates and their development are examined. The related research was performed for chelates with chain structure. This book is useful to researchers being active in synthesis and design of macromolecular metal chelates
