Four oxovanadium and one dioxovanadium complex with 2-hydroxyacetophenone N(4)-phenylthiosemicarbazone (H(2)L) which are represented as [VOLphen].2H(2)O (1), [VOLbipy] (2), [VOLdmbipy] (3), [VOL](2) (4) and [VO(2)HL].CH(3)OH (5) have been synthesized and characterized by elemental analyses, electronic, infrared and EPR spectral techniques. In all the complexes 1-4 the ligand coordinates through...

Upon mixing of oxovanadium(IV) acetylacetonate, this complex caused an increase in the chemiluminescence (CL) of luminol in a reverse micellar medium of cetyltrimethylammonium chloride in chloroform-cyclohexane (6:5 vlv)-water (buffered with NaOH-Na2C03, pH 12.5) even in the absence of an oxidizing reagent such as hydrogen peroxide. In this CL process, the reaction of Luminol with the oxovanadi...

Schiff bases have been synthesized by the reaction of triazole containing primary amine with aromatic carbonyl compounds. The prepared, act as ligand when these are made in contact oxovanadium (VO2+) ion. Some new mononuclear oxovanadium(IV) complexes base ligands vanadyl sulphate (VOSO4.xH2O) and analyzed different spectroscopic methods; [fourier-transform infrared (FTIR), ultraviolet-visible ...

rounding the oxovanadium(IV) species, VO 2~ , in particular the 70 or so papers published since my more comprehensive review. 1 Complexes of V02+ and their examination by X-ray diffraction, infrared spectroscopy, thermodynamic (stability) studies, electron spin resonance studies, and electronic spectral studies, and attempts at theoretical models, are critically reviewed and updated. [The SCP8 ...
