在水热条件下合成了新型超分子化合物(bipyH2)2(H2P2Mo5O23)*H2O, 对其进行了红外光谱、拉曼光谱、紫外-可见漫反射光谱、荧光光谱和循环伏安等分析表征. X射线单晶结构分析表明, 标题化合物属单斜晶系, P21/c空间群, 晶胞参数a=1.679 51(7) nm, b=1.151 93(4) nm, c=1.889 08(8) nm, β=108.335(1) °, V=3.469 2(2) nm3, Z=4, Dc=2.382 g/cm3, F(000)=2 408, μ=1.951 mm-1, R=0.024 4, Rw＝0.072 1. 标题化合物的杂多阴离子[P2Mo5O23]4-由5个MoO6畸变的八面体和2个PO4畸变四面体通过共顶点或共边组成; 5个Mo原子近似处于同一平面, 它们和2个P原子组成了一个畸变的五角双锥构型; 杂多阴离子与质子化的4,4′-bipy和水分子通过氢键连成无限二维网状结构, 形成超分子化合物.
