A Novel Ni(II) Coordination Polymer Constructed From Organic Acid and Bis(imidazol) Ligand: Hydrothermal Synthesis, Crystal Structure, and Electrochemical Properties

A novel coordination polymer, [Ni(BDC)(bix)(H2O)] (H2BDC = 1,4-benzenedicarboxylic; bix = 1,4-bis(imidazol-1-ylmethyl) benzene), has been synthesized under hydrothermal conditions and structurally characterized by elemental analyses, IR spectroscopy, and single X-ray diffraction. Ni(II) ion in a distorted octahedral coordination environment and bix plays a bidentate bridging ligand to conform the 2D square grid structure which is expands to the 3D structure through the hydrogen bonds. The thermal and electrochemical properties of complex were investigated as well.
