✦ Synopsis

IR and Raman studies of the low-and high-temperature phases of LiIn(MoO 4 ) 2 were performed at ambient temperature. The crystal structure of the low-temperature modi5cation was solved. The observed vibrational modes were assigned to the vibrations of respective atoms in the unit cells. The origin of brown coloration and unusual shift of stretching vibrations toward higher energy, observed for the low-temperature polymorph, were explained as a result of instability of wolframitetype structure containing MoO 6 octahedra.

## Abstract 2,6‐Diphenyl‐1,4‐dithiin **2** exists in the two polymorphic forms. The dithiin **2L**, mp 62–63°C, was assigned as the metastable form, while the dithiin **2H**, mp 79–80°C, was assigned as the stable form, mainly on the basis of differential scanning calorimetry (DSC) analysis. X‐Ray
