摘要
Two new 3d-4f heterometallic coordination Polymers, [LnCu(nic)(2)(ox)]center dot 2H(2)O (Ln = Sm(1), Dy (2), ox = oxalate anion, Hnic = nicotinic acid) were synthesized and characterized by elementary analysis, IR spectroscopy and thermogravimetric analysis, as well as single-crystal X-ray diffraction. The two structures exhibit the same unusual 3D microporous heterometallic coordination frameworks with 13.7 % voids occupied by guest water molecules.
