Book excerpt: Molecular stereochemistry is a fundamental aspect of all areas of chemistry. It is especially important in inorganic chemistry where the coordination numbers are variable and occasionally quite high. The present book evolved naturally from a series of articles written by Professor Kepert for Progre88 in Inorganic Ohemi8try, elucida ting aspects of the stereochemistry of inorganic compounds of co ordination numbers 4-12. In the present volume, Professor Kepert has added new sections and synthesized these individual chapters into a unified treatment, updating his references when necessary to the most recent contributions in the literature, and inter weaving the various themes as deemed appropriate. The result is a major contribution, describing the stereochemistry of coordi nation compounds having both unidentate and multidentate ligands. The viability of the repulsion approach to stereochemistry is tested to the limit in this treatise and shown to be an extremely good way of rationalizing a diverse body of data.
