Some peculiarites of chemical bond in A II B V 2 systems from the data on the magnetic susceptibility of the A II B V 2 compounds and their solid solutions are discussed. With this aim in view the magnetic susceptibility has been divided into the Langevin diamagnetic and van Vleck paramagnetic terms. The diamagnetic susceptibility of valence electrons, affecting the chemical bond in a crystal against the covalency parameter along the A – B, A – A, B –B bonds in A II B V 2 compounds, has been analysed. The covalency parameter of the A II B V 2 compounds has been evaluated. Closeness of the covalency parameter values for monoclinic β‐ZnP 2 and tetragonal CdP 2 , CdAs 2 , is evidently, one of the reasons for the solid solution formation between the above mentioned compounds.
