摘要：

It is shown that coordination numbers (CN) of alkali atoms can be determined in crystal structures by means of Voronoi-Dirichlet polyhedra without using crystal-chemical radii. It is found that a domain with constant volume corresponds to an alkali atom at CN greater than or equal to 6. The conclusion about correctness of application of the model of deformable spheres for the description of alkali atoms in a crystal field is drawn.
