The transmitted light intensity (TLI) and polarized optical microscopy (POM) measurements of [Mn(OS(CH3)2)6](ClO4)2 and [Zn(OS(CH3)2)6](ClO4)2, as a function of temperature, showed that only some of the phase transitions discovered earlier for these compounds by the differential scanning calorimetry were now observed as anomalies on the TLI curves and as different textures in POM pictures. Above-mentioned methods indicated that discovered phases of both compounds were the crystalline phases with different orientational dynamical disorder. Additionally, it was confirmed that these both compounds melt at 488 and 465 K, respectively.
