| Abstract: A ligand cinnamaldehyde salicylhydrazone(C16H14N2O2, HL) and its Ni(Ⅱ) complex, [NiL2(DMF)2]·(DMF)2 have been synthesized and its ingredients, structure and Electrochemical Properties were characterized by the element analysis, IR spectrum, X-ray single crystal diffraction structural analysis and cyclic voltammetry, respectively. The complex crystallizes in monoclinic, space group P21/n with cell parameter a=11.160 1(12) nm, b=18.919(2) nm, c=11.997 4(13) nm, β=115.694(2)°, and V=2 282.7(4) nm3, Z=2, Dc=1.289 g·cm-3. The crystal structure reveals that the center nickel(Ⅱ) cation is bonded to two ligands and two solvent DMF molecules to form an octahedral coordination geometry. The bioactivity test shows that the Ni(Ⅱ) complex of cinnamaldehyde salicylhydrazone has selective antibacterial property against S. Aureus and B. Subtilis. CCDC: 722241. |
