This book was released on 1981 with total page 25 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have been examining the solvent dependence of the thermodynamics of simple transition-metal redox couples as part of an experimental program exploring the role of the solvent in the kinetics and thermodynamics of outer-sphere electron transfer reactions. One-electron redox couples containing substitutionally inert complexes form especially tractable systems for this purpose since the influence of variations in the outer-shell solvent contributions can be assessed separately from the inner-shell (metal-ligand coordination shell) effects. Our general approach is to determine the formal potential Ef of each redox couple in a range of solvents having suitably varied chemical and physical properties. In addition, the temperature dependence of Ef is monitored in each solvent using a nonisothermal cell arrangement, yielding values of the reaction entropy of the redox couple equals the difference between the absolute ionic entropies of the reduced and oxidized forms. These measurements yield estimates of the free energy, entropy, and enthalpy of transferring the redox couple from water to other solvents.

Download or read book Solvent Ligand and Ionic Charge Effects on Reaction Entropies for Simple Transition Metal Redox Couples written by J. T. Hupp and published by . This book was released on 1984 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dependence of the reaction entropies for simple M(III)/(II) redox couples, with M = Ru, Fe, Os, Cr, upon the nature of the ligands and the solvent is examined with a view towards correlating the entropies with simple physical parameters. For couples containing ammine, ethylenediamine, polypyridine, cyclopentadiene or psuedohalide ligands reaction entropy in a given solvent is found to correlate well with a function of the charge numbers of the oxidized and reduced forms, and with 1/r, where r is the effective radius of the redox couple. This suggests that shortrange ligand-solute interactions do not provide a predominant contribution to reaction entropy for these systems, although this effect is probably important for aquo redox couples in water. The dependence of reaction entropy upon the solvent correlates reasonably well with the solvent acceptor number and other solvent polarity parameters.

Available in PDF, EPUB and Kindle. Book excerpt: In order to use rare earths successfully in various applications, a good understanding of the chemistry of these elements is of paramount importance. Nearly three to four decades have passed since titles such as The Rare Earths edited by F.H. Spedding and A.H. Daane, The chemistry of the Rare Earth Elements by N.E. Topp and Complexes of the Rare Earths by S.P. Sinha were published. There have been many international conferences and symposia on rare earths, as well as the series of volumes entitled Handbook of Physics and Chemistry of Rare Earths edited by K.A. Gschneidner and L. Eyring. Thus, there is a need for a new title covering modern aspects of rare earth complexes along with the applications. The present title consists of twelve chapters. 1. Introduction2. General aspects3. Stability of complexes4. Lanthanide complexes5. Structural chemistry of lanthanide compounds6. Organometallic complexes7.

Download or read book Cage Metal Complexes written by Yan Voloshin and published by Springer. This book was released on 2017-05-11 with total page 475 pages. Available in PDF, EPUB and Kindle. Book excerpt: This fundamental book presents the most comprehensive summary of the current state in chemistry of cage metal complexes. After their previous book “The Encapsulation Phenomenon” (www.springer.com/978-3-319-27737-0) the authors in this book focus on the encapsulation of metal ions by different types of three-dimensional mono- and polynucleating caging ligands. Within these cage metal complexes, (metal) ions can be isolated from external factors. The book provides both a classification of the cage compounds and summaries of synthetic approaches. On that basis the authors then describe the unique chemical and physical properties and the resulting reactivity of the cage compounds, as well as practical and potential applications as potent topological drugs and prodrugs, antifibrillogenic agents, radiodiagnostic and radiotherapeutic compounds, paramagnetic probes, single-molecule magnets, electrocatalysts for hydrogen production, (photo)electronic devices, and many more. Readers will find a well-structured and concise overview, with particular emphasis on a review of synthesis and reactivity of various cage metal complexes, summarizing over 400 literature references, clearly presented in over 300 color schemes and figures.
