The synthesis conditions, composition, structure, and properties of the com
pounds formed in the A(II)((BUO6)-U-V)(2)-H2O systems (A(II) = Mn, Fe, Co,
Ni, Cu, Zn; B-V = P, As) were studied. The X-ray powder patterns and spectr
oscopic and thermodynamic characteristics of the above compounds were obtai
ned. The relations between their structure and physicochemical properties a
nd features of the electronic structure of A(II) and B-V were considered.
