Syntheses and Crystal Structures of Cd(II) and Zn(II) Complexes Containing 2-Acetylpyridine-o-aminobenzoylhydrazone Ligand

Two complexes [CdL(NO3)(2)center dot H2O] (1) and [ZnL2] (2) were synthesized by the reaction of Schiff base ligand (2-acetylpyridine-o-aminobenzoylhydrazone) (L) with Cd(NO3)(2)center dot 4H(2)O or Zn(CH3COO)(2)center dot 2H(2)O respectively. The compounds are characterized by H-1 NMR, FTIR, and elemental analysis. The structures of the two complexes are analyzed via single crystal X-ray diffraction. The results show that the complex 1 crystallizes in monoclinic, space group P2(1)/n, and the complex 2 crystallizes in monoclinic, space group P2(1)/c. The antibacterial activities of the ligand and complexes were measured in vitro, and the results show that the ligand L and complex 1 possess inhibiting effects to bacteria.
