Two　novel　monooxovanadium(V)　complexes　[VOL1(bz)]　(1)　(H2L1=N-salicylideneglycine,　Hbz=benzohydroxamic　acid)　and　[VOL2(bz)]·(CH3OH)　(2)　(H2L2=N-(2-carboxyphenyl)salicylidenamine),　were　prepared　and　characterized　by　IR,　Raman,　UV,　1H　NMR　spectra,　cyclic　voltammetry　measurements　and　X-ray　diffraction.　The　vanadium　atoms　in　the　two　title　complexes　have　a　distorted　octahedral　geometry　with　VO(ONO)　(OO)　type　coordination.　The　equatorial　plane　is　defined　by　the　O,　N,　O　atoms　of　the　tridentate　ligand　and　the　oxime　oxygen　atom　of　the　benzohydroxamate　ligand.　The　oxo　group　is　trans　to　the　carbonyl　oxygen　atom　of　the　hydroxamate　ligand,　but　not　to　the　oxime　oxygen　atom　of　the　same　ligand.　The　two　title　complexes　represent　the　first　structural　characterization　of　a　vanadium　hydroxamate　complex　with　VO(ONO)　(OO)　coordination.　©　1998　Elsevier　Science　S.A.　All　rights　reserved.
