以钼-矾磷酸盐(PMo_(12)V_2O_(46)~(5-))和4,4′-联吡啶(bpy)为混合配体,水热合成了一种新的多酸基化合物[(H_5PMo_(12)V_2O_(46))(bpy)2](1),并通过红外、热重和单晶X-射线衍射对其结构进行了表征。结果表明,该化合物属单斜晶系,P2(1)/n空间群,晶胞参数为:a=11.431(2)A,b=12.214(2)A,c=17.269(4) A,V=2351.6(8)(?)3,Z=2,R_1=0.0676,wR_2=0.1986。同时,标题化合物的热稳定性和电化学性质也被研究。
A new polyoxometalate compound was synthesized by the hydrothermal method using molybdenum-alum phosphate (PMo_ (12) V_2O_ (46) ~ (5-)) and 4,4’-dipyridyl (H_5PMo_ (12) V_2O_ (46)) (bpy) 2] (1), and its structure was characterized by IR, TG and single crystal X-ray diffraction. The results show that the compound belongs to the monoclinic space group P2 (1) / n with unit cell parameters of a = 11.431 (2) A, b = 12.214 (2) A, c = 17.269 = 2351.6 (8) (?) 3, Z = 2, R_1 = 0.0676, wR_2 = 0.1986. At the same time, the thermal and electrochemical properties of the title compound have also been investigated.
