Abstract

Complex formation between ammonium trioxovanadate(V) and imidazole has been studied and characterized by FT IR, UV/Vis, thermal analysis (TG, DTA, DTG) and polarographic techniques. Species formed in solid phase yield a yellow coloured product exhibiting an absorbance maximum at 400 nm. The FT IR spectra show that the inclusion of imidazole has a significant influence on the structure and the hydrogen bonding pattern in NH4VO3. Species formed in aqueous solution has been examined by voltammetry. Formation of an adduct of trioxovanadate(V) with imidazole onto dropping mercury electrode followed by reduction of the sample in DCP of the complex in 0.05 M NH3/NH4Cl buffer (pH 9.08) resulted in a single peak at -0.875 V.
