| Abstract: A new copper(Ⅱ) complex CuL(py)(HL=2,4-Dihydroxyacetophenone-5-bromo-salicylacylhydrazone) was synthesized by the reaction of Cu(CH3COO)2·H2O with 2,4-dihydroxyacetophenone-5-bromo-salicylacylhydrazone in the ethanol. It was characterized by elemental analysis, IR and X-ray single crystal structure analysis. The crystal belongs to monoclinic, space group P21/c with a=0.5693 7(11) nm, b=3.991 4(7) nm, c=0.881 17(17) nm, β=107.149(3)°, V=1.913 5(6) nm3, Z=4, Dc=1.756 Mg·m-3, μ=3.263 mm-1, F(000)=1 012, and final R1=0.048 3, wR2=0.106 3. The crystal structure indicates that the copper(Ⅱ) lies in a distorted square-planar environment composed of two oxygen atoms, one nitrogen atom from the tridentate acylhydrazone ligand and one nitrogen atom from the pyridine ligand. The molecules are packed in two-dimensional network structure though intermolecular hydrogen bonds formed adjacent molecules. CCDC: 684932. |
