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.
