SYNTHESIS, SPECTRAL CHARACTERIZATION AND ELECTROCHEMISTRY OF VANADIUM(V) COMPLEX WITH TRYPTOPHAN
A new oxovanadium(V) complex of NH4VO3 and tryptophan (TrpH) has been synthesized in aqueous solution at pH 6.0 and characterized by elemental analysis, UV-Vis, FT-IR, ¹H-NMR and mass spectroscopic data. The complex (Na4[V3O9(Trp)]) was diamagnetic in nature as was evident from the electrón spin res...
