- Аннотация: Single crystals of the new zeolite-like copper diphosphate chloride |(NH4)5(H2O)9CaVCl3(OH)|[(Cu6(P2O7)4Cl3] were prepared by the hydrothermal synthesis route. The crystal structure of the new com-pound was studied by X-ray diffraction using synchrotron radiation (λ = 0.64066 Å) at T = 100 К (R = 0.052):a = 17.9357(5) Å, c = 13.5377(4) Å, sp. gr. I4/mcm, Z = 4, ρcalc = 2.541 g/cm3. A copper tetramer is the mainstructural unit, which is formed by four CuO4Cl pyramids sharing a vertex occupied by a Cl atom. The clustersof the composition Cu4O12Cl are connected through diphosphate groups and additional Cu-centered poly-hedra to form a mixed-type open framework. Large channels in the framework are occupied by , V4+,and Ca2+ cations, (OH)– and Cl– anions, and H2O molecules. Similar complex ionic inclusions are charac-teristic of a series of homeotypic copper diphosphate chlorides exhibiting ion-exchange properties.
