The crystal structure of new manganese potassium copper vanadate KCuMn3(VO4)3, which was prepared by the hydrothermal synthesis in the K2CO3–CuO–MnCl2–V2O5–H2O system, was studied by X-ray diffraction (R = 0.0355): a = 12.396(1) Å, b = 12.944(1) Å, c = 6.9786(5) Å, β = 112.723(1)°, sp. gr. C2/c, Z = 4, ρcalc = 3.938 g/cm3. A comparative analysis of the crystal-chemical features of the new representative of the alluaudite family and related structures of minerals and synthetic phosphates, arsenates, and vanadates of the general formula A(1)A(1)′A(1)″A(2)A(2)′M(1)M(2)2(TO4)3 (where A are sites in the channels of the framework composed of MО6 octahedra and TО4 tetrahedra) was performed. A classification of these structures into subgroups according to the occupancy of A sites is suggested.
