摘要：
The crystal structures of two vanadyl phosphates, Rb(VO2)[HPO4] (a = 7.029(4) Å, b = 9.513(6) Å, c = 18.049(10) Å, sp. gr. Pbca, Z = 8, ρcalcd = 2.910(3) g/cm3) and CsAl(VO)[PO4]2(H2O) (a = 8.0128(13) Å, b = 8.0714(13) Å, c = 14.118(2) Å, β = 106.302(2)°, sp. gr. I21/c, Z = 4, ρcalcd = 3.295(1) g/cm3), obtained by hydrothermal synthesis, have been refined using X-ray diffraction (Bruker Smart diffractometer, T = 100 K). Hydrogen atoms are located, and their coordinates and thermal parameters are refined. The geometric characteristics of hydrogen bonds are calculated and their crystallochemical function is analyzed. The topological and genetic relationships of the vanadyl phosphates under study with the compounds of derivative structural types are revealed.
