One Novel Vanadium-Phosphate Cluster [PV_(2.5)O_(8.5)]-3.83{H_2O} with Three-Dimensional Architecture

A novel vanadium-phosphate compound [PV_2.5O_8.5]·3.83{H_2O}(1)was obtained from the hydrothermal reac-tion and structurally characterized by elemental analysis and single-crystal X-ray diffraction,which exhibited thatthe 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,D_c=1.783 g/cm~3,F(000)=2278,R_1=0.0528,and wR_2=0.1329[I>2σ(I)](all data).The basic unit of{PV_2.5O_8.5}symmetrically extended to closed sphere-like structure of{P_4V_(10)O_(34)},which was further linked to in-terleaving three-dimensional network via sharing four phosphate through μ_3-oxygen atoms around the closedsphere-like structures.     

钒磷构筑的三维无机化合物[PV2.5O8.5]·3.83(H2O)的合成和晶体结构表征

以偏矾酸铵和磷酸氢二铵通过水热反应得到具有三维结构的无机钒-磷化合物，用X-射线单晶衍射方法测定了它的结构，该晶体空间群为I-43m，a = 16.1148(2) Å, V = 4184.80(9) ų, z = 12, Dc = 1.783 g/cm³, F(000)= 2278, R₁ = 0.0528, and wR₂ = 0.1329 [I>2σ(I)]。 在该化合物中，基本单元{PV_2.5O_8.5}首先对称性地组合成封闭球形结构{P₄V₁₀O₃₄}, 进一步通过磷酸桥连成三维空间结构。
