SYNTHESIS AND VIBRATIONAL STUDIES OF OXOVANADIUM(IV) - TETRADENTATE SCHIFF-BASE COMPLEXES

The two new Schiff base complexes of oxovanadium (IV) {[}VO(acac-en)] (acac-en = bisacetylactone - ethyl-enediimino) and {[}VO(sal-o-phdn)] (sal-o-phdn = N,N'-o-phenylenebis (salicylideneiminato) have been prepared. The infrared spectra of the solid complexes have been obtained and assigned on the bases of C(S) symmetry. A polymeric chain structure with V-O-V bridge has been adopted for the both complexes.
