Problem in coordination chemistry

While 61Ni Mossbauer spectroscopy has proven valuable in solid-state chemistry, its application to problems in coordination chemistry is very rare. The parent 61Co nucleus (/ /2 99 min) serves as the... 

The sandwich structure of bis (benzene) chromium (XXV) prepared by this new route was soon confirmed by Weiss and Fischer (242). Moreover, Fischer and Sens (98) prepared bis (phenyl) chromium iodide (XXII) by the Friedel-Crafts-type method, starting with biphenyl in place of benzene, and were able to show that the product obtained in this manner was identical to bis (biphenyl) chromium iodide (XXII) isolated via Heines Grignard route. A longstanding and vexing problem in coordination chemistry was thus finally solved.

CCCII comprises ten volumes, of which the last contains only subject indexes. The first two volumes describe the development of new ligands since the 1980s, which complements Volume 2 in CCC. They also include new techniques of synthesis and characterization, with a special emphasis on the burgeoning physical techniques which are increasingly applied to the study of coordination compounds. Developments in theory, computation methods, simulation, and useful software are reported. The volumes conclude with a series of case studies, which illustrate how synthesis, spectroscopy, and other physical techniques have been successfully applied in unravelling some significant problems in coordination chemistry. 

The mechanisms of surface chemical reactions represent a problem in coordination chemistry, which is the study of complexes, molecular units comprising a central group surrounded by other atoms in close association. This book is principally an introduction to the interpretation of surface phenomena in soils from the point of view of coordination chemistry. Therefore the basic concept to be discussed is the surface functional group, the central moiety in surface complexes, whose formation provides the most important mechanism of adsorption by the solid phases in soils. No detailed consideration of adsorption isotherm equations or the thermodynamic theory of ion exchange is presented, except insofar as their tenuous relation with surface coordination chemistry is to be illustrated. The discussion in this book is intended to be self-contained, but a previous exposure to soil physical chemistry, soil mineralogy, and the fundamentals of inorganic chemistry will prove helpful. 

About 25 % of Jensen s papers deal with problems in coordination chemistry. An examination of the "Science Citation Index" shows that even today Jensen s production has an annual score of about 100 citations. 25 of these are to his early papers in ZeitscMftfur anorganische und allgemeine Chemie, Considering the statistical fact that the citation rate of an average paper is 1.7, culminating a few years after the appearance, Jensen s unusually high score is a testimony to the importance of his worlc... 

The solution to many important problems in coordination chemistry begins with synthesis but the development of a synthetic method is not necessarily an end in itself. Coordination compoimds are employed in many areas of chemistry and other fields. Often problem solving begins with synthesis and the synthesis may be performed by those relatively unfamiliar with the discipline. The authors hope that this text, that deals with synthetic coordination chemistry, will be usefol to those engaged in the preparation of coordination compounds for which a variety of end uses are likely.
