摘　　要：在水热条件下,利用AgNO_(3)、磷钼酸(H_(3)PO_(4)·12MoO_(3))和4-(1H-1,2,4-三唑-1-甲基)苯甲酸(简写为H_(2)L)为原料,我们合成了一个新的多钼酸盐(H_(3)L)_(3)(PMo_(12)O_(40))·2H_(2)O。对该化合物进行了热重分析(TG)、红外光谱分析(IR)和X-射线单晶衍射分析等结构表征。X-射线单晶衍射结果表明,在该化合物的结构中,水分子通过氢键相互作用力将相邻多酸上的端氧原子O34及桥氧原子O12连接形成1D超分子链,质子化的有机配体H_(3)L+与多酸和水之间的氢键相互作用力将相邻的1D超分子链连接起来形成3D的超分子结构。并对该化合物光催化降解有机染料的性质进行了研究,发现该化合物可以有效地降解有机染料亚甲基蓝。A new polyoxomolybdate,(H_(3)L)_(3)(PMo_(12)O_(40))·2H_(2)O(H_(2)L=4-(1H-1,2,4-triazole-1-methyl)benzoic acid),was synthesized under hydrothermal conditions by using AgNO_(3),phosphomolybdic acid(H_(3)PO_(4)·12MoO_(3))and 4-(1H-1,2,4-triazole-1-methyl)benzoic acid as raw materials.The structure of the compound was characterized by TGA,IR and X-ray single crystal diffraction.In the structure of the compound,water molecules connected the terminal oxygen atom O34 and the bridge oxygen atom O12 in the adjacent polyacids through hydrogen bonds to form a one-dimensional supramolecular chain which was further connected by each other via hydrogen bonds to form a three-dimensional supramolecular structure.The photocatalytic properties of the compound were studied.The results showed that it had good degradation efficiency for methylene blue.
