Polyhedra have cropped up in many different guises throughout recorded history. In modern times, polyhedra and their symmetries have been cast in a new light by combinatorics an d group theory. This book comprehensively documents the many and varied ways that polyhedra have come to the fore throughout the development of mathematics. The author strikes a balance between covering the historical development of the theory surrounding polyhedra, and presenting a rigorous treatment of the mathematics involved. It is attractively illustrated with dozens of diagrams to illustrate ideas that might otherwise prove difficult to grasp. Historians of mathematics, as well as those more interested in the mathematics itself, will find this unique book fascinating.

This beautiful model to cut out and glue together is the result of arranging five interpenetrating cubes in a highly symmetrical way. Each cube is printed in its own color and so it is easy to see that exactly two cubes meet at every vertex and that there are twelve surfaces defining each face of each cube. There is a strong internal frame and multiple divisions in the golden ratio to discover.

- Up-to-date compilation of the experimental data on the structures of binary compounds by Villars and colleagues. - Coloured structure maps which order the compounds into their respective structural domains and present for the first time the local co-ordination polyhedra for the 150 most frequently occurring structure types, pedagogically very helpful and useful in the search for new materials with a required crystal structure. - Crystal co-ordination formulas: a flexible notation for the interpretation of solid-state structures by chemist Bill Jensen. - Recent important advances in understanding the quantum mechanical origin of structural stability presented in two clearly-written chapters by leading experts in the field: Hafner, Majewski and Vogl. ``The Structures of Binary Compounds'' presents not only the most up-to-date compilation of the experimental data on the structures of binary compounds, but also the recent important theoretical advances in understanding the quantum-mechanical origin of structural stability. In addition to this volume, a large wall chart displaying the structure maps for the AB, ABs and AB3 stoichiometries together with the corresponding co-ordination polyhedra, has been published.The first half of the book details the successful ordering of the known experimental data in two- or three-dimensional coloured structure maps, the 150 most frequently occurring structure types being characterized for the first time by their local co-ordination polyhedra. The second half of the book details the success of first-principle theoretical calculations within the Local Density Functional Approximation in predicting the correct ground state structures of binary semiconductors, insulators and metals. The book concludes with a chapter on the cohesion and structure of solids from the more localized tight-binding point of view.

The study of crystal structures has had an ever increasing impact on many fields of science such as physics, chemistry, biology, materials science, medicine, pharmacy, metallurgy, mineralogy and geology. Particularly, with the advent of direct methods of structure determination, the data on crystal structures are accumulating at an unbelievable pace and it becomes more and more difficult to oversee this wealth of data. A crude rationalization of the structures of organic compounds and the atom coordinations can be made with the well-known Kekule model, however, no such generally applicable model exists for the structures of inorganiC and particularly intermetallic compounds. There is a need to rationalize the inorganic crystal structures, to find better ways of describing them, of denoting the geometrical relationships between them, of elucidating the electronic factors and of explaining the bonding between the atoms with the aim of not only having a better understanding of the known structures, but also of predicting structural features of new compounds.
