One new mixed-ligand coordination polymer,namely[Co_2(btc)(bpdc)_(0.5)(py)_3]_n(1),was hydrothermally synthesized using biphenyl-2,4,4’-tricarboxylic acid(H_3btc) as a main building block,along with two auxiliary ligands(H_2bpdc = 2,2’-bipyridine-5,5’-dicarboxylic acid and py =pyridine).The product 1 was characterized by IR spectroscopy,elemental,thermogravimetric,and single-crystal X-ray diffraction analyses.Single-crystal X-ray diffraction studies show that compound 1 possesses an intricate 3D metal-organic framework based on tetracobalt(Ⅱ) units.Magnetic susceptibility measurement indicates that compound 1 shows an antiferromagnetic coupling between the Co(Ⅱ) ions.
