Description
Summary: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 (H 2 O) 6 ][HSiMo 12 O 40 ] 2 ·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 (H 2 O) 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.
