Abstract
Alkali-metal and ammonium salts of yellow oxydiperoxychlorovanadates(V), A2[V0(02)2C1], and blue triperoxychlorovanadates( V), A2[V(02)3CI] (A = Na, K, or NH4), have been synthesized, for the first time, by reacting V205 with alkali chloride, AC1, and hydrogen peroxide in varying concentrations of alkaline media. The three salts of the anion [VO(02)2C1]2- are comparatively more stable than those of the complex anion [V(02)3Cl]2-. Characterization of the compounds has been made from the results of elemental analyses, magnetic susceptibility measurements, and IR spectroscopic studies. The IR spectra suggest that the peroxy groups are bonded to vanadium(V) in a triangular bidentate manner and that the 0-0 bond order of peroxy ligands decreases with the increase in the number of peroxy ligands coordinated to the metal center. The conversion of [VO(02)2Cl]2- to [V(02)3Cl]2- and the reverse provide good evidence for the facile diperoxyvanadate( V)-triperoxyvanadate(V) interconversion.
