摘　　要：A new three-dimensional 3d-4d heterometallic coordination polymer,[Cd2Mn（H2O）4（BTC）2]·2H2O（BTC=1,3,5-benzenetricarboxylate） was prepared under hydrothermal conditions and characterized by single crystal X-ray diffraction.This compound crystallized in the monoclinic space group C2/c,with cell parameters a=1.9452（4） nm,b=0.7094（2） nm,c=1.8064（4） nm,β=118.02（3）°,V=2.2004（8） nm3 and Z=4.Its structure contains trinuclear mixed metal clusters,which are further connected by BTC to form a three-dimensional framework.The compound exhibits intense photoluminescence at room temperature.Magnetic studies of the compound show a dominant antiferromagnetic exchange between the Mn（Ⅱ） ions.A new three-dimensional 3d-4d heterometallic coordination polymer,[Cd2Mn（H2O）4（BTC）2]·2H2O（BTC=1,3,5-benzenetricarboxylate） was prepared under hydrothermal conditions and characterized by single crystal X-ray diffraction.This compound crystallized in the monoclinic space group C2/c,with cell parameters a=1.9452（4） nm,b=0.7094（2） nm,c=1.8064（4） nm,β=118.02（3）°,V=2.2004（8） nm3 and Z=4.Its structure contains trinuclear mixed metal clusters,which are further connected by BTC to form a three-dimensional framework.The compound exhibits intense photoluminescence at room temperature.Magnetic studies of the compound show a dominant antiferromagnetic exchange between the Mn（Ⅱ） ions.
