Abstract
- Two new oxidovanadium(V) complexes, [VO(L)(L)] ( I) and [VO(L)(L)] ( II), where L and L are the dianionic form of N'-(2-hydroxy-5-methoxybenzylidene)pivalohydrazide (HL) and N'-(2-hydroxy-3-methoxybenzylidene)pivalohydrazide (HL), respectively, and L is the monoanionic form of 8-hydroxyquinoline (HL), were prepared and characterized by elemental analysis, infrared and electronic spectra, and H NMR spectra. Structures of the complexes were further confirmed by single crystal X-ray determination (CIF files CCDC nos. 1477854 ( I), 1477856 ( II)). HL and HL coordinate to the V atoms through the phenolate O, imino N, and enolate O atoms. 8-Hydroxyquinoline coordinates to the V atoms through bidentate ON donor set. The V atoms of the complexes are in octahedral coordination with the oxo group furnished the octahedral geometry. The complexes show effective antibacterial activity against Bacillus subtilis.
