摘  要:利用H3PMo12O40.4H2O,4,4′-bipy和AgNO3反应,在中温水热条件下合成了一种新颖的三维超分子多金属氧酸盐(4,4′-bipy){[Ag(4,4′-bipy)]3[PMo12ⅥO40]}.H2O(1),并通过元素分析、红外光谱、热重分析和X射线单晶衍射对其结构进行了表征.结果表明,该化合物属三斜晶系,P1空间群,晶胞参数a=1.1275(2)nm,b=1.1910(2)nm,c=1.2898(3)nm,α=112.63(3)°,β=94.63(3)°,γ=99.53(3)°,V=1.5567(5)nm3,Z=1.该化合物具有三维超分子结构及荧光性质.Abstract A new 3 D supramolecular compound, (4,4′-bipy) [Ag (4,4′-bipy) ] 3 [ PMo12^ⅥO40] · H2O ( 1 ) was synthesized under mild hydrothermal condition, and the structure was characterized by elemental analysis, single crystal X-ray diffraction, IR and TGA. Compound 1 exhibits a photoluminescence property at room temperature. The structure of this compound consists of [ PMo12 O40 ] ^3- anion, which is further connected by [Ag(4,4′-bipy) ] 3^+ unit to form a three-dimesional supramolecular network. Compound 1 crystallized in the triclinicsystem, space group P^-1, a =1.1275(2) nm, b = 1.1910(2) nm, c = 1.2898(3) nm, α = 112.63(3)°,β=94.63(3)°, γ=99.53(3)°, V=1.5567(5) nm^3, Z =1.
