Abstract

Three new sulfides Li2CdSnS4 (1), Na2CdSnS4 (2) and Na6CdSn4S12 (3), have been synthesized using a molten flux of alkali-metal polysulfides and structurally characterized by single crystal X-ray diffraction studies. Both the layered compound 1 and the three-dimensional compound 2 have tetrahedral anionic frameworks of (CdSnS4)2− and, for charge compensation, alkali-metal cations. The two-dimensional compound 3 has Na+ ions interleaved between anionic (CdSn4S12)6− layers with an octahedral framework. Compounds 1, 2 and 3 are structurally related to Cu2CdGeS4, LiAlSe2 and Na2SnS3 respectively. Compound 2, as determined from its diffuse reflectance spectrum, is a semiconductor with a band gap of 1.52 eV.
