Tl2CS3 is Indium-like structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of four Tl2CS3 clusters. Tl(1) is bonded in a 1-coordinate geometry to one S(1) atom. C(1) is bonded in a trigonal planar geometry to one S(2) and two equivalent S(1) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a distorted L-shaped geometry to one Tl(1) and one C(1) atom. In the second S site, S(2) is bonded in a distorted single-bond geometry to one C(1) atom.
