摘　　要：通过饱和溶液蒸发法,合成了一个零维配位聚合物H_(2)[Cu_(2)(tztrz)_(3)·6H_(2)O][PMo_(12)O_(40)]·18H_(2)O(1)[tztrz=5-(4H-1,2,4-三氮唑-4-基)-四氮唑],并通过X-射线单晶衍射、红外光谱和热重对配合物进行了表征。X-射线单晶衍射分析结果显示,配合物结晶于三方晶系R3c空间群。单胞中含有一个磷钼酸,一个双核铜单元,十八个游离水分子。其中双核铜单元由两个Cu离子与三个tztrz以及六个水分子相连而形成,展现出一个有趣的“Y”字型构型。配合物1对罗丹明B染料展现出较强的催化降解能力,经紫外灯照射300 min后降解率高达76.6%明显优于单纯的磷钼酸。此外,配合物1在催化反应后易从体系中分离出来并重复使用,催化能力没有明显下降。By saturated solution evaporation,a 0D coordination polymer H_(2)[Cu_(2)(tztrz)_(3)·6H_(2)O][PMo_(12)O_(40)]·18H_(2)O,(1),[tztrz=5-(4H-1,2,4-triazol-4-yl)-2H-tetrazole]has been isolated and characterized by X-ray single crystal diffraction,IR and TG.The single crystal X-ray diffraction analysis reveals that complex 1 crystallizes in the trigonal crystal system with the R3c space group.The unit of complex 1 consists of a PMo_(12) polyoxoanion,a di-nucleus Cu unit and eighteen dissociative water molecules.The di-nucleus Cu unit is composed of two Cu ions,three tztrz ligands and six water molecules,which display an interesting“Y”type coordination mode.Complex 1 displays good photocatalytic activities for rhodamine B dye.After UV light irradiation 300 min,the photocatalytic decomposition rate is 76.6%,which was significantly better than that of using insoluble(NBu_(4))_(3)[PMo_(12)O_(40)].In addition,complex 1 can easily separated from the reaction system for reuse and the photocatalytic activity does not exhibit significant decrease after five runs in the same photocatalytic tests.
