Synthesis and structural characterization of two coordination polymers constructed by bis(4-(1H-imidazol-1-yl)phenyl)methanone and 5-(tert-butyl)isophthalate ligands

Two coordination polymers, {[Co(bipmo)(tbip)]·3H 2 O} n ( 1 ) and {[Cd(bipmo)(tbip)]·3H 2 O} n ( 2 ) (bipmo=bis(4-(1 H -imidazol-1-yl)phenyl)methanone, H 2 tbip=5- tert -butylisophthalic acid), were synthesized by solvothermal methods and structurally characterized by elemental analyses, infrared spectroscopy, and single-crystal X-ray diffraction. The results from single-crystal X-ray diffraction data indicate that the solid state structures of 1 and 2 consist of metal-aromatic carboxylate layers, which are pillared by weak interactions to generate a three-dimensional network. The topological structures of 1 and 2 are uninodal nets based on 3-connected nodes with the Schläfli symbol of {6 3 }.
