Synthesis and Structural Characterization of a Nickel Coordination Polymer Based on 4-(1H-Imidazol-1-yl)phenyl)methanone with Phthalic Acid.

Abstract: A nickel coordination polymer with V-shaped ligands, {[(L1)2Ni(H2O)2] · 2(C8H5O4)}n, (L1 = 4-(1H-imidazol-1-yl)phenyl)methanone) has been synthesized under the solvothermal conditions. The structure has been determined by the single-crystal X-ray diffraction analysis and characterized by the infrared spectroscopy and elemental analysis. The crystal is crystallized in the monoclinic sp. gr. P21/c with the unit cell parameters a = 15.6387(3) Å, b = 8.0526(2) Å, c = 24.4791(6) Å, and β = 129.2350(10)°, Z = 2. The adjacent [Ni(H2O)2] units are linked by two bridging L1 ligands to form 1D looped chains, which are extended by the hydrogen bonds to yield a 3D framework. [ABSTRACT FROM AUTHOR]
