新奇钒磷酸盐混合物[PV2.5O8.5 ]
A novel vanadium-phosphate compound [PV2.5O8.5]·3.83{H2O} (1) was obtained from the hydrothermal reaction and structurally characterized by elemental analysis and single-crystal X-ray diffraction, which exhibited that the title complex crystallized in cubic space group I-43m with crystal data: a= 1.6115(1) nm, V=4.1848(1) nm^3, Z=12, Dc=1.783 g/cm^3, F(000)=2278, R1=0.0528, and wR2=0.1329 [1〉2σ(I)] (all data). The basic unit of {PV2.5O8.5} symmetrically extended to closed sphere-like structure of {P4V10O34}, WhiCh was further linked to interleaving three-dimensional network via sharing four phosphate through μ3-oxygen atoms around the closed sphere-like structures.
