It is high time for a first-rate new book on crystals, especially the unique ad of stereo viewing facilities. This survey of the important types of inorganic and organic crystal structures treats its subject thoroughly and in sufficient depth for undergraduate modules in chemistry courses. Features of this book are the instructions for 3D stereoviewing which is central to a full appreciation of the presentation. Clear directions for making your own stereo have been provided in the book, which enable readers to examine the plentiful stereo of lattices and crystal structures which are illustrated. The introductory chapter explains point-group and space-group symmetry insofar as required to understand lattices and crystal structures. Crystal structures are sub-divided according to the atomic force mainly responsible for cohesion in the solid state, the descriptions of the structures are gi in crystallographic terms, including data on the space group, molecular symmetry and molecular geometry. Discussions of bonding theory for each sub-division of the structures enhance and strengthen the authorβs presentation. The book stems from the authorβs successful lecture courses, tested and refined in class teaching. It draws as necessary on equilibrium thermodynamics and other chemical topics, with avoidance of advanced mathematics, A level being the prerequisite.
