✦ Synopsis

Measurements of the dielectric properties of Sn 2 P 2 S 2X4 Se 3X6 crystals at submillimeter wavelengths indicate that there are two structural phase transitions of incommensurate±ferroelectric and para-electric±incommensurate in this material at temperatures T C 224 K and at about T i 230 K.
