Abstract
TlSnPS4 crystallizes in the orthorhombic system, space group Pna21 (Nr. 33), Z = 4 with the lattice constants a = 1175.8 (5) pm, b = 890.1 (4) pm, c = 663.3 (4) pm. In the structure are sligthly distorted discrete PS3- 4 anions. The far infrared, infrared and Raman spectrum is assigned on the basis of PS3- 4 -units with C3 v symmetry. According to the DTA data the melting point for TlSnPS4 is 575 ± 5 °C. The title compound is not moisture sensitive and semi-conducting.Keywords
