TlCrS2 is Calaverite-derived structured and crystallizes in the trigonal R3m space group. Cr(1) is bonded to three equivalent S(1) and three equivalent S(2) atoms to form edge-sharing CrS6 octahedra. Tl(1) is bonded in a 6-coordinate geometry to three equivalent S(1) and three equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 3-coordinate geometry to three equivalent Cr(1) and three equivalent Tl(1) atoms. In the second S site, S(2) is bonded in a 3-coordinate geometry to three equivalent Cr(1) and three equivalent Tl(1) atoms.
