SYNTHESIS AND SPECTROSCOPIC STUDIES ON OXOVANADIUM COMPLEX WITH LIGANDS HAVING N, N-DONOR SITES

The present investigation is concerned with a method by the reaction of vanadylsulphate with nitrogen containing ligands N, N donor sites like dicyandiamide, methyldicyandiamide and phenyldicyandiamide in methanol and refluxed. The tentative structure of these complexes has been proposed on the basis of elemental analysis, magnetic moment and spectral (IR, EPR) data. The IR and EPR spectra of all the complexes were recorded at room temperature and at liquid nitrogen temperature. The room temperature EPR spectrum shows anisotropy because the band is observed separately.
