摘　　要：以3-(1H-四氮唑-1-乙酸酰胺)吡啶(TAAP)、 Anderson型多金属氧酸盐和氯化铜为原料,用水热合成方法制备一种新的基于四氮唑配体(HTrz=1H-四氮唑)和Anderson型多酸的铜配合物{H2Cu12(Trz)12[CrMo6(OH)6O18]2(OH)8(H2O)4}·12H2O.晶体结构解析表明:该化合物先由去质子化的四氮唑配体Trz通过铜离子连接形成金属-有机二维层,再通过多酸阴离子[CrMo6(OH)6O18]3-端氧连接二维层上的铜离子形成三维框架结构;在水热合成过程中配体TAAP原位转化成Trz.合成的配合物对H2O2有良好的电催化还原效果,在紫外光下对亚甲基蓝和结晶紫有良好的催化降解效果.Using the 3-(1H-tetrazole-1-acetic acid amido)pyridine(TAAP),Anderson-type polyoxoanions and copper chloride as raw materials,we synthesized a new Anderson-type polyoxometalate-based copper complex{H 2Cu 12(Trz)12[CrMo 6(OH)6O 18]2(OH)8(H 2O)4}·12H 2O(HTrz=1H-tetrazole).The crystal structure analysis shows that the complex is a two-dimensional metal-organic layer formed by Trz ligand and Cu 2+ions.The terminal oxygen atoms of the[CrMo 6(OH)6O 18]3-polyoxoanions is connected to the Cu 2+ions to further form a three-dimensional coordination framework.In situ conversion of TAAP ligand to Trz during the hydrothermal synthesis.The synthesized complex has good electrocatalytic reduction effect on H 2O 2,and good catalytic degradation effect on methylene blue and crystal violet under ultraviolet light.
