The book is an introduction to the doctrine of the structure of inorganic compounds. It can serve as a valuable addition to ordinary textbooks on inorganic chemistry, in which, as a rule, this material is considered very fluently. The book consists of two parts: the first includes the main ideas of the theory of structure, including such issues as the theory of the solid state, liquids, solutions and elements of chemical kinetics, the second is devoted to the description of the structure of inorganic compounds.
