The chemistry of this most abundant element has two major aspects: that of water and aqueous solutions of electrolytes, and that of the solid state. The methodology and techniques appropriate for the study of these fields are sufficiently different that there have been very few points of contact between solution- and solid state chemists. One such contact, of great potential value, is provided by the extensive class of polyoxoanions formed by the transition metals of groups 5 and 6 As ‘heteropoly and isopoly acids’ these polyanions have been known and investigated for more than a century. The present book -is an attempt to survey the chemistry, structures, and applications of these species. Although the book forms part of a series in inorganic chemistry, the field of polyoxometalates deserves wider attention, for example, from organic chemists, especially those concerned u'ith homogeneous and heterogeneous catalysis, and from biochemists, solid state- and materials scientists. Following an introductory chapter which provides a brief historical review and discusses limitations of experimental techniques, Chap. 2 is intended to give a general overview of the field: synthetic methods, common structures, properties, and applications. Chapters 3 and 4 are comprehensive reviews of isopolyanions and heteropolyanions respectively. Some of the special properties of polyanions, their use as ligands and eryptands, and their extensive and complex redox chemistry (‘heteropoly blues’ ) are described in Chap. 5 and 6 The relatively recent and expanding subfield of polyanions containing organio and organometallic groups is desoribed in Chap. 7, and in the final chapter some views on the limits of the field and the mechanism of formation of polyanions are presented.
