Construction of Two New Coordination Polymers Based on the Semirigid Dicarboxylate and Imidazole-Containing Ligands

摘要

Two new coordination polymers, {[Cd(bda)(bib)]·H_2O}n (1) and {[Co(bda) (bib)]·H_2O}n (2) (H_2 bda = benzophenone-2,4α- dicarboxylic acid, bib = 4,4-bis(1-imidazol-yl) -2,5- dimethyl benzene), have been synthesized and characterized by IR, element analysis and single X-ray diffraction. Complexes 1 and 2 are all two-dimensional structure. Complex 1 shows a three-dimensional supramolecular structure through the hydrogen bonding interactions. In 2, the 2D layers adopt AB packing mode.
