Three mononuclear nickel(II), cadmium(II) and zinc(II) complexes, [NiL2]·2CH3OH·H2O (1), [CdI2(HL)]·CH3OH (2) and [ZnL2] (3), have been synthesized from 3-hydroxy-4-methoxy-N'-[(Z)-(pyridin-2-yl)methylidene]benzohydrazide (HL) by microwave irradiation method. All complexes were characterized by CHN elemental analyses and infrared spectra. Structures of the complexes were further studied by single crystal X-ray determination, which reveals that the Ni and Zn atoms in complexes 1 and 3 are in octahedral coordination, and the Cd atom in complex 2 is in square pyramidal coordination. The biological activity of the complexes on the bacterial strains Bacillus subtilis, Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli was evaluated. As a result, the zinc complex has interesting antibacterial activities.
三种单核镍（II）、镉（II）和锌（II）配合物，[NiL2]·2CH3OH·H2O（1）、[CdI2(HL)]·CH3OH（2）和[ZnL2]（3），已通过微波辐射法从 3-羟基-4-甲氧基-N'-[(Z)-(吡啶-2-基)亚甲基]苯甲酰肼（HL）合成。所有配合物均通过 CHN 元素分析和红外光谱进行了表征。配合物的结构进一步通过单晶 X 射线测定进行了研究，结果表明配合物 1 和 3 中的 Ni 和 Zn 原子处于八面体配位，而配合物 2 中的 Cd 原子处于四方锥配位。还评估了配合物对枯草芽孢杆菌、金黄色葡萄球菌、铜绿假单胞菌和大肠杆菌这几种细菌菌株的生物活性。结果表明，锌配合物具有有趣的抗菌活性。
