Abstract:

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.
