Abstract

An inorganic-organic hybrid crystalline mate-rial(SiMo12O40)[Cu(2,2'-bipy)2]2·2H2O(Complex 1,2,2'-bipy=2,2'-bipyridine)was synthesized for the first time by using 2,2'-bipy and transition metal copper to convert Waugh-type polyoxometalate[MnMo9O32]6-into a Keg-gin polyoxometalate structure[SiMo12O40]4-under hydrothermal conditions in glass vials.Single crystal tests and a series of characterizations were carried out on Complex 1.The structure of Complex 1 is composed of[SiMo12O40]4-and[CuⅡ(2,2'-bipy)2]2+.The five-coordi-nated Cu is connected to two 2,2'-bipy through Cu-N bonds,forming an approximately square structure.Aston-ishingly,Complex 1 exhibited good photocatalytic performance for methylene blue degradation and electro-catalytic nitrite reduction properties simultaneously.
