Synthesis,crystal structure and luminescent properties of a thiocyanato bridged two-dimensional heteronuclear polymeric complex of cadmium(II)and copper(II)

摘要

A novel heteronuclear polymeric complex Cd(SCN)3Cu(en)2NO3(1)(en=ethylenediamine)has been synthesized and structurally characterized.The Cd(II)atom is surrounded by three S atoms and three N atoms from four 1,3-mu-SCN~-and two 1,1,3-mu-SCN~-to attain a distorted octahedral coordination geometry.Six Cd(II)centers are linked by twelve thiocyanato bridges to form hexagonal metallocyclic unit[Cd6(SCN)12]and extend a 2D network.Moreover,a 1,1,3-mu-SCN~ links two cadmium and one copper metal atoms.The luminescent properties of 1 in the solid state were investigated.
