Abstract

Raman measurements were carried out on aqueuos indium nitrate solutions containing different additives (NaNO3, HNO3 and NaOH), on a crystalline hydrate In(No3)3·3H2O, and on its melt. Band envelope fitting in the region of InO stretching vibrations (350 to 550 cm-1 yielded component bands which were assigned to different types of complexes present in the solutions: (i) 485 cm-1: the totally symmetric 'breathing' vibration of InO(H2) bonds in hexa-aquo indium cations, [In(H2O)6]3+; (ii) 406 cm-1: InO vibrations of a partly hydroxylated aquo complex of indium; (iii) 465 and 425 cm-1: InO(H2) vibrations of aquo complexes containing one or more nitrate ions in the first coordination sphere of indium. Depolarization ratios of the Raman bands in the 1200 to 1550 cm-1 region allowed us to decide whether mono- and bidentate nitrate complexes of indium are formed in some of these systems.
