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

Two novel complexes, {[ L 1 Ni(ipa)(H 2 O)] 2 (DMF)} n ( 1 ) and {[ L 1 Zn(pa)] 4 (H 2 O)} n ( 2 ), ( L 1 = bis(4-(1 H -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 }.
