STRUCTURAL CHARACTERISTICS OF DOUBLE VANADATES (V) ON THE BASIS OF ALKALI AND ALKALINE-EARTH METALS
The procedure of structural characteristics (interstructural distances, radiuses) calculation of the substances crystallized in various singonies and structures has been developed. The procedure has been tested on alkali metals and alkaline-earth double vanadates (V). The basis for calculations of structural characteristics of the crystalline substances consisting of several various cations, the composite anions or polyanions has been proposed.
