Raman spectra of Mg(ClO 4 ) 2 NaNCSH 2 O mixtures were analysed as a function of the concentration ratio of the components at ambient and elevated temperatures. The strong perturbation of the thiocyanate spectrum observed in the regions of the ν 1 and ν 3 vibrations is interpreted in terms of complex formation. Band intensity measurements of resolved bands gave evidence for two complex species: [MgNCS] + and [Mg(NCS) 2 ], the former being discernible over the whole concentration range studied. The variations in the spectrum of the T d perchlorate ion at very low water‐to‐salt molar ratios are explained as indicating a coordination of ClO 4 − unit and lowering of the symmetry of C 2ν .
