摘要
The aroylhydrazone Schiff base ligands [N'-(2-hydroxynaphthyl)ethylidene]-4-nitrobenzohydrazide (H2La) and N'-(3,5-dichloro-2-hydroxybenzylidene)- 3-nitrobenzohydrazide (H2Lb) reacting with VO(acac)(2) in methanol gave the complexes [VOLa(OMe)]center dot 0.5MeOH center dot 0.6H(2)O (1) and [VOLb(OMe)(MeOH)] (2). Both complexes were characterized by elemental analyses and IR spectroscopic method in the solid state. Single crystal X-ray analysis was performed, which indicates that both complexes are mononuclear. The V atom in (1) is in a square pyramidal geometry, and that in (2) is in an octahedral geometry. V-IV in VO(acac) 2 was oxidized to V-V in the complexes by aerial oxygen during the synthesis and crystallization. Antibacterial activities of the aroylhydrazone ligands and the complexes have been studied on the strains Bacillus subtilis, Escherichia coli, and Staphylococcus aureus.
