Abstract: The ternary compound thallium bismuth disulfide crystallizes in the space group R
m and is isotypic with the structures of most of the ABQ2 chalcogenides (A = monovalent atom, B = trivalent atom and Q = chalcogen), which are members of the ![[alpha]](/logos/entities/alpha_rmgif.gif)
-NaFeO2 structure type. In the title compound, the Tl and Bi atoms are situated on positions with m symmetry, whereas the S atom sites exhibit 3m symmetry. The metal atoms occupy octahedral voids in distinct planes perpendicular to the c axis. The environment around Tl is more distorted than the polyhedron around Bi.
