Synthesis and structural characterization of oxovanadium(V) complexes with mixed tridentate benzohydrazone and bidentate no ligands
TL;DRAbstract
New oxovanadium(V) complexes, [VO(L1)(Bha)] (I) and [VO(L2)(Qnl)] (II), were prepared by the reactions of [VO(Acac)2] (Acac = acetylacetonate), (4-nitrophenoxy)acetic acid [1-(2-hydroxy-3-methylphenyl)methylidene]hydrazide (H2L1) and benzohydroxamic acid (HBha), and [VO(Acac)2], N′-(2-hydroxy-5-methylbenzylidene)-3-methylbenzohydrazide (H2L2), and 8-hydroxyquinoline (HQnl) in methanol, respectively. Crystal and molecular structures of complexes I and II were determined by elemental analysis, infrared and UV-Vis spectra and single crystal X-ray diffraction (CIF files CCDC nos. 1000875 (I) and 1012028 (II)). The V atoms in the complexes are in octahedral coordination. Thermal stability of complex I was studied.
