A novel metal-organic coordination polymer, [Ni-2(dipic)(2)(4,4'-bpy)4(H2O)].4H(2)O (H(2)dipic = pyridine-2,6-dicarboxylic acid), has been hydrothermally synthesized and characterized by elemental analysis, IR, TG and single crystal X-ray diffraction. Blue crystals crystallized in the monoclinic system, space group P2(1)/c, a = 10.582(2) Angstrom, b = 20.246(4) Angstrom, c = 7.2501(15) A,beta = 105.73(3)degrees, V = 1495.0(5) Angstrom(3), Z = 2 and R = 0.0377. The structure of the compound exhibits a novel three-dimensional supramolecular network, formed by hydrogen-bonding and pi-pi stacking interactions. lnterestingly, the three-dimensional network consists of one-dimensional trapezoid channels, which accommodate lattice water molecules.
