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

A nickel coordination polymer with V -shaped ligands, {[( L 1 ) 2 Ni(H 2 O) 2 ] · 2(C 8 H 5 O 4 )} n , ( L 1 = 4-(1 H -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. P 2 1 / 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(H 2 O) 2 ] units are linked by two bridging L 1 ligands to form 1D looped chains, which are extended by the hydrogen bonds to yield a 3D framework.
