A New Ni(II) Coordination Polymer Based on Imidazole-Containing and Dicarboxylate Ligands with Polycatenated 2D + 2D → 3D Framework

Abstract

A new coordination polymer, {[Ni(sdb)(bimb)1.5]·H2O} (1) (H2sdb = 4,4'-sulfonyl- dicarboxylic acid and bimb = 1,4-bis(1-imidazol-yl)-2,5-dimethyl benzene) has been prepared by hydrothermal synthesis and characterized by elemental analysis, IR, and X-ray diffraction. Complex {[Ni(sdb)(bimb)1.5]·H2O} (1), monoclinic, space group P21/c with a = 13.494(5)Å, b = 14.313(5) Å, c = 17.803(5) Å, β = 97.792(5)°, V = 3407(2) Å3, Z = 4, Mr = 738.43, Dc = 1.440 g/cm3, F(000) = 1532, and µ = 0.689 mm−1. The final refinement gave R = 0.0351and wR = 0.0950 for 6688 reflections with I > 2σ(I). X-ray diffraction analysis reveals that complex 1 shows a three-dimensional 2D + 2D → 3D Framework.
