Phase polymorphism of [Zn(OS(CH3)2)6](ClO4)2 studied by vibrational spectroscopy.
The FT-IR and FT-RS spectra of [Zn(OS(CH3)2)6](ClO4)2 measured in the spectral range of 4000-90cm(-1) in a function of temperature show distinct differences before and after all three observed phase transitions. The study of temperature dependence of the band position and full width at half maximum allowed us to link each of the observed phase transitions (at: TC1(h)≈355K, TC2(h)≈341K and TC3(h)≈315K) with the changes either of the crystal structure or with the reorientational motions of the dimethylosulphoxide (DMSO) ligands and/or [Zn(OS(CH3)2)6](2+) and/or the ClO4(-) anions and/or with all these changes together.
