We present our attempts to prepare lamellar SnP 2 S 6 and CuInP 2 S 6 by metathesis reactions in aqueous media. Use of a SnCl 4 precursor unexpectedly led to the formation of the three-dimensional compound Sn II 2 P 2 S 6 rather than Sn IV P 2 S 6 . The crystallites thus obtained were about 65 nm in
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.
