摘要：
A pair of new mononuclear zinc(II) complexes with hydrazone ligands 4-methoxybenzoic acid (1-pyridin-2-yl-methylidene)hydrazide (HLa) and benzoic acid (1-pyridin-2-ylethylidene)hydrazide (HLb) were prepared. They are [Zn(L-a)(2)] (1) and [Zn(L-b)(2)] (2). The complexes were characterized by physico-chemical methods and single crystal X-ray determination. The tridentate hydrazone ligands coordinate to the Zn atoms through the pyridine nitrogen, imino nitrogen and enolate oxygen atoms. The Zn atom in each complex is six coordinated by two hydrazone ligands, to form octahedral coordination. The complexes have effective activities against the bacteria Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas fluorescens.
