Özet:

 

The monooxovanadium(V) complex of composition  [VO(OC6H3(NO2)2-2,4)3] (I) was synthesized by the reaction of  VOCl3 with Me3SiOC6H3(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 (I) with alkali metal  2,4-dinitrophenoxides [MOC6H3(NO2)2-2,4] (M = Li, Na, K) yield  complex salts of composition M[VO(OC6H3(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.
