| Abstract | ||
| In this work; Vanadium (V) chelate complex derived from tetradenate Schiff base (L) Chloro- Oxo ( bis ( p- hydroxyl benzaldehyde ) ethylene diiminato ) Vanadium (V) complex was synthesized and characterized. The photochemical decomposition is investigated by Infrared and ultraviolet spectroscopy. The kinetics of the photochemical reaction of this complex when irradiated with light of λ=365 nm at 25◦ C was studied in four different organic solvent ,with different polarity .These solvents were CCI4,dimethyl sulfoxide (DMSO),1,4 dioxane and CHCI3.It was found that the rate of photodecomposition of this complex is first order and also dependent on polarity of the solvent. The mechanism of photochemical decomposition of (VOLCI) in these solvents was elucidated by adopting the spectra technique (Uv-visible and infrared ) observations suggest that an intra oxidation –reduction reaction in this complex occur to breaking of(V-CI) bond and the formation chlorine atom and Vanadium (1v) complex(V1VOL). | ||
