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。
In this paper, a kind of polyoxoanion [NH3 (CH2) 4NH3] [H2pip] 2 [V10O28] .6H2O (1, pip = piperazine) was synthesized by hydrothermal technique and characterized by elemental analysis, Compound 1 was characterized by X-ray crystallography. Compound 1 is monoclinic and has a space group of P21 / n with unit parameters of a = 1.229 85 (10) nm, b = 1.075 10 (9) nm, c = 1.496 71 (12) nm and β = 93.947 0 (10) °, V = 1.974 3 (3) nm3, Z = 2. The crystal structure analysis showed that compound 1 was composed of [V10O28] 6-anion cluster, protonated 1,4-butanediamine and piperazine cation and crystal water. The organic cations and the water of crystallization connect the anions to form a three-dimensional structure through the interaction of O-H ... O and N-H ... O hydrogen bonds.
