Abstract
Abstract Raman spectra have been used to investigate the cation-solvent interaction in acetone solution of Mg(CIO4)2. Analysis of the bands of C=O and C-C valence vibrations of acetone and the totally symmetric vibration of CIO4 ion led to the identification of different magnesium-acetone associations. The stability of the formed solvate species has been tested by adding NaSCN to solution. It is found that all bands arising from the solvated acetone molecules to the Mg2+ ion are changed in the presence of NaSCN and the new bands, attributed to the other species, occur. Formation of the magnesium-isothiocyanato complexes in solution has been supported by the analysis of the symmetric stretching ν1 (C-N) vibration of the SCN ion.
