Syntheses, Structural Characterization of Nickel and Zinc Coordination Polymers Composed of Dicarboxylate and Bis(4-(1H-benzo[d]imidazol-1-yl)phenyl)methanone Ligands

Two novel complexes, {[(LNi)-Ni-1(ipa)(H2O)](2)(DMF)}(n) (1) and {[(LZn)-Zn-1(pa)](4)(H2O)}(n) (2), (L-1 = bis(4-(1H-benzo[d]imidazol-1-yl)phenyl)methanone, H(2)ipa = isophthalic acid, H(2)pa = phthalic acid) were obtained and structurally characterized. Treatment of M(OAc)(2) (M = Ni, Zn) with a dicarboxylic acid and L-1 under solvothermal conditions gave the title complexes in moderate yields. The complexes were characterized by elemental analysis, IR spectroscopy and X-ray diffraction. Complex 1 represents 1D chains along the b axis, and complex 2 shows 2D network with the point symbol {4(4).6(2)}.
