Synthesis and characterization of a new copper(II) coordination polymer with mixed ligands of tetrabromoterephthalic acid and imidazole
A new copper(II) coordination polymer containing mixed ligands of tetrabromoterephthalate (Br4tp) and imidazole (Im), [Cu(Br4tp)(Im)(H2O)] (1), was successfully synthesized and characterized by single crystal X-ray diffraction, powder X-ray diffraction, elemental analysis, infrared spectroscopy, and thermogravimetric analysis. The single crystal X-ray diffraction analysis at 100(2) K and 296(2) K revealed that 1 crystallizes in the centrosymmetric monoclinic with space group C2/c, and displays a two-dimensional sheet with a binodal (3,4)-connected net. Compound 1 exhibited thermal stability up to 240 °C.
