Abstract
The Raman spectra of solutions in acetone of crystalline salts with anionic stoicheiometries HgX3-, HgX42-, Hg2X5-, and Hg3X82- (where X = Cl, Br, or I) were determined. The dominant species identified in all cases except (pyH)2HgI4 was HgX3- which probably had a bent (C3v) configuration. The species Hg2I5- was also identified in solutions of Me4NHg.2I5. The disproportionation reactions are discussed in terms of ion-solvent interactions.
