    Abstract:
    The reaction of Cu(NO3)2·3H2O with 2,4'-oxybis(benzoic acid) and 4,4'-bipyridine under hydrothermal conditions produced a new mixed-ligand two-dimensional copper(II) coordination polymer, namely poly[[(μ-4,4'-bipyridine-κ2N,N')[μ-2,4'-oxybis(benzoato)-κ4O2,O2':O4,O4']copper(II)] monohydrate], {[Cu(C14H8O5)(C10H8N2)]·H2O}n, which was characterized by elemental analysis, IR spectroscopy, thermogravimetric analysis and single-crystal X-ray diffraction. The X-ray diffraction crystal structure analysis reveals that the CuII ions are connected to form a two-dimensional wave-like network through 4,4'-bipyridine and 2,4'-oxybis(benzoate) ligands. The two-dimensional layers are expanded into a three-dimensional supramolecular structure through intermolecular O-H...O and C-H...O hydrogen bonds. Furthermore, magnetic susceptibility measurements indicate that the complex shows weak antiferromagnetic interactions between adjacent CuII ions.
