spectra. Structures of the complexes were further confirmed by single crystal X-ray diffraction (CIF files CCDC nos. 1477847 (I), 1477850 (II)). H2L coordinates to the V atom through the two enolic O atoms and the imino N atom. The ligands Ehp and Aha coordinate to the V atoms through bidentate OO donor set. The V atoms of the complexes are in octahedral coordination, with the oxo group furnished the
两种新的氧化钒(V)络合物[VO(L)(Ehp)](I)和[VO(L)(Aha)](II),其中L是4-溴-N '-(4 -Oxopentan-2- Ydylene)benzohydrazide (H 2 L),Ehp是2-乙基-3-羟基-4 H -pyran-4-one(HEhp)的单阴离子形式,而Aha是乙酰氧肟酸的单阴离子形式(制备并通过元素分析,红外和电子光谱以及1 H NMR光谱进行表征。配合物的结构通过单晶X射线衍射进一步确认(CIF文件CCDC No.1477847(I),1477850(II))。H 2 L通过两个烯属的O原子和亚氨基N原子配位至V原子。配体Ehp和Aha通过双齿OO供体组与V原子配位。配合物的V原子处于八面体配位状态,羰基提供了八面体几何形状。该配合物对枯草芽孢杆菌具有有效的抗菌活性。
