Abstract
Raman and infrared spectra have been measured of solutions of oxides of metals of Groups VIA, VA, and IVA in aqueous hydrofluoric, hydrochloric, and perchloric acids. Evidence was obtained for the existence in such solutions of fluoro- and chloro-complexes of molybdenum and tungsten with cis-dioxo-ligands, of mono-oxo-pentahalogeno-species of niobium and vanadium, and of unsubstituted halogeno-complexes of tantalum, titanium, zirconium, and hafnium. Polynuclear complexes were formed in perchloric acid solutions.
