Abstract :The monooxovanadiuminsert ignore into journalissuearticles values(V); complex of composition [VOinsert ignore into journalissuearticles values(OC6H3insert ignore into journalissuearticles values(NO2);2-2,4);3] insert ignore into journalissuearticles values(I); was synthesized by the reaction of VOCl3 with Me3SiOC6H3insert ignore into journalissuearticles values(NO2);2-2,4 in toluene and characterised by elemental analyses, molar conductance, and IR, 1H- and 13C-NMR, and mass spectral studies. The reactions of insert ignore into journalissuearticles values(I); with alkali metal 2,4-dinitrophenoxides [MOC6H3insert ignore into journalissuearticles values(NO2);2-2,4] insert ignore into journalissuearticles values(M = Li, Na, K); yield complex salts of composition M[VOinsert ignore into journalissuearticles values(OC6H3insert ignore into journalissuearticles values(NO2);2-2,4]4 authenticated by physicochemical and IR spectral studies. Thermal behaviour of complexes was studied by TG and DTA techniques. The molecular modelling calculations of the parent complex and its complex salts were performed to visualise the probable geometry around vanadium metal, which, coupled with spectroscopic evidence, suggests a distorted tetrahedral and a trigonal-bipyramidal geometry for respective complexes.
