Abstract

The oxovanadium(IV) complexes of the Schiff base hydrazones, synthesized from 3-hydrazinoquinoxaline-2-one (HQO) with salicylaldehyde (HSHQO), o-hydroxyacetophenone (HHAHQO), dehydroacetic acid (HDHAHQO) and o-nitrobenzaldehyde (NBHQO) were synthesized and characterized on the basis of analytical, conductance, magnetic moment, infrared, NMR, ESR and electronic spectral data. The ligands HSHQO, HDHAHQO behaved as monobasic tridentate ONN donors through phenolic oxygen, azomethine nitrogens. The ligand HAHQO acted as a monobasic bidentate ON donor through the phenolic oxygen, azomethine (free) nitrogen and the ligand NBHQO acted as neutral bidentate ON donor through oxygen of the nitro group and azomethine (free) nitrogen.
