摘　　要：本文采用水热技术合成了一种多钒氧酸盐[NH3(CH2)4NH3][H2pip]2[V10O28].6H2O(1,pip=哌嗪),并且通过元素分析、红外、热重、单晶X-射线衍射对化合物1进行了表征。化合物1为单斜晶系,空间群为P21/n,晶胞参数为a=1.229 85(10)nm,b=1.075 10(9)nm,c=1.496 71(12)nm,β=93.947 0(10)°,V=1.974 3(3)nm3,Z=2。晶体结构分析表明,化合物1是由[V10O28]6-阴离子簇、质子化的1,4-丁二胺和哌嗪阳离子以及结晶水构成。有机阳离子和结晶水通过O-H…O和N-H…O氢键相互作用将阴离子连接形成三维结构。A polyoxovanadate [NH3（CH2）4NH3][H2pip]2[V10O28]·6H2O （1, pip=piperazine） has been synthesized by hydrothermal method and characterized by elemental analysis, IR, TGA and single-crystal X-ray diffraction. Compound 1 crystallizes in the monoclinie system, soace arouo P21/n. with cell oarameters of a=1.22985（10）nm,b=1.07510（9）nm,c=1.49671（12）am,/3=93.9470（10）°,V=1.9743（3）nm^3,Z-2. Crystallographic analysis reveals that it is constructed from anionic cluster [V10O28]^6-, protonated 1,4-butanediamine and piperazine cations, as well as waters of crystallization. Organic cations and waters of crystallization further connect the anions into a threedimensional framework by water-anion hydrogen bonds O-H…O and cation-anion N-H.…O interactions. CCDC： 848090.
