This multi-author volume addresses a number of currently important aspects of materials chemistry. Topics covered in separate chapters include molecular inorganic superconductors, molecular inorganic magnetic materials, metal-containing materials for nonlinear optics, inorganic intercalation compounds, biogenic inorganic materials, clay chemistry, polymeric coordination complexes, metal-containing liquid crystals and precursors for electronic materials.

The choice of authors for these chapters is definitely not a traditional one and features younger workers with European and British affiliations. This results in a refreshingly different point of view in many of the chapters dealing with areas most familiar to this reviewer. It would, however, have been helpful to have had the authors and their affiliations indicated in the table of contents, which looks misleadingly like that of a single-author volume.

The format of the chapters is in most cases similar, consisting of a reasonably detailed introduction to the basic principles relevant to a given area, followed by a review of work published in the last ten to twenty years. The inclusion of background material makes the text a very nice way of introducing the areas to a more general readership. The coverage is reasonably up-to-date, with only two chapters having no references prior to 1991 and several including references to work published in 1992. The breadth of coverage in the contributions varies substantially; some authors concentrate heavily on work from their own laboratory (e.g. molecular inorganic superconductors) while others provide a broader survey of established (e.g. intercalation chemistry) or developing (e.g. nonlinear optical materials) areas. The overall effect, however, is an approach that is distinctive without being idiosyncratic.

Thus, Chapter 1, on molecular inorganic superconductors (P. Cassoux & L. Valade, 58 pp.), is a case history of work in the authors' laboratories on metal-dmit complexes. The writing is perhaps overly dramatic for most tastes, with phrases such as `the holy grail was found' and `the fire of hope was ... kept burning', but the chapter gives a good review of the requirements for molecular superconductors. Chapter 2 (O. Kahn, Y. Pei & Y. Journaux, 46 pp.) provides a detailed introduction to magnetic phenomena in solids and a good description of the correlation between structural and magnetic properties. After a thorough discussion of the physical principles underlying second- and third-order nonlinear optical phenomena, Chapter 3 (S. R. Marder, 50 pp.) provides a reasonably detailed review of the relevant properties of inorganic materials. The chapter on intercalation chemistry (Chapter 4, by D. O'Hare, 70 pp.) focuses on specifics without developing underlying principles; for example, oxidation of nitrogenous guests by metal dichalcogenides is probably a general phenomenon and is not restricted solely to the ammonia and pyridine systems cited.

Probably the most intriguing chapter is that on biogenic materials. (Chapter 5, by S. Mann, 57 pp.). It provides an excellent overview of this relatively unfamiliar area. The discussion of synthetic strategies to mimic such materials by using assembly in compartments or at monolayers, or molecules designed to interact specifically with a growing crystal surface, is compelling, despite the skepticism of some well regarded senior figures in the materials community. The chapters on clays (Chapter 6, by R. W. McCabe, 56 pp.) and on polymeric coordination complexes (Chapter 7, by G. E. Kellogg & J. Gaudiello, 52 pp.) are much more in the nature of traditional reviews. In contrast, the chapter on metal-containing liquid crystals (Chapter 8, by D. W. Bruce, 86 pp.) provides a good introduction to liquid crystals in general, followed by a survey of methods used to incorporate metals. The final chapter (Chapter 9, by P. O'Brien, 44 pp.), on precursors to electronic materials, starts with a brief survey of electronic materials and growth methods and then focuses on III/V and II/VI systems, with a brief summary of methods applied to the high-Tc oxides. The book concludes with a very brief index that is too cursory to be useful.

Overall, the book is an asset to the literature. The production (from camera-ready copy) is remarkably free of errors and the individual chapters are likely to be useful to relative newcomers as well as to experts in a given area. As an introduction to the excitement and promise of inorganic materials, it is clearly worth reading. The relative lack of emphasis on the detailed structures of the materials discussed, or on the methods used to elucidate them, may make the book of only peripheral interest to the practising crystallographer, but it provides a good introduction to new and potentially interesting areas of research.
