electronic spectroscopy. Structures of the complexes were further confirmed by single crystal X-ray determination. The V atoms in the complexes are in octahedral coordination. The hydrazone ligands coordinate to the V atoms through the phenolate O, imino N, and enolate O atoms. The hydroxamate ligand coordinates to the V atom through the carbonyl and hydroxy O atoms. The complexes show effective antibacterial
两个新的氧化钒(V)络合物[VOL 1 L](1)和[VOL 2 L]·CH 3 OH(2·CH 3 OH),其中L 1和L 2是N'-(3 -溴-2-羟基亚苄基)吡啶并酰肼(H 2 L 1)和2-氯-N'-(2-羟基-3-甲氧基亚苄基)苯并酰肼(H 2 L 2),L是2-的单阴离子形式制备了羟基苯并异羟肟酸(HL),并通过元素分析,红外和电子光谱对其进行了表征。通过单晶X射线测定进一步证实了配合物的结构。络合物中的V原子处于八面体配位状态。hydr配体通过酚盐O,亚氨基N和烯醇化O原子与V原子配位。异羟肟酸酯配体通过羰基和羟基O原子配位至V原子。该复合物显示出对B的有效抗菌活性。枯草杆菌,金黄色葡萄球菌和大肠杆菌。复合物中Cl取代基的存在可以增强抗菌活性。
