摘要：

By introducing mixed organic ligands (pytz and 4,4'-bipy) into a Keggin POM system, a new Keggin POM-based supramolecular compound, [Cu-3(bipy)(4)(pytz)(2)(H2O)(6)][HSiMo12O40](2)center dot 8H(2)O (1) (pytz = 5-(pyridyl)tetrazolate, bipy = 4,4'-bipy) was hydrothermally synthesized and characterized by routine methods. Crystal structure analysis reveals that the title compound contains both right- and left-helical chains, and these helical chains are further connected together forming an interesting mesh network via sharing the [Cu-3(bipy)(4)(pytz)(2)(H2O)(6)] subunits. Finally, the 1D pillar-like chains link the mesh nets to construct a 3D supramolecular structure of 1. In addition, compound 1 shows good photocatalytic activity for the degradation of Rhodamine B dye.
