| Abstract: | Quaternary sulfides MPb8In17S34 (M = Cu, Ag, Au) were synthesized at 1123 K from their elements in stoichiometric ratios. These compounds crystallize in monoclinic space group P2(1)/m. The crystal structures feature combinations of 2[InS2] (NaCl111-type) and [MPb2In3S6] (NaCl100-type) slabs. These compounds are semiconductors with band gaps near 1.3 eV. |
