The structure described by Tl2Sn2S3 crystallizes in the monoclinic C2/c space group. Tl(1) is bonded in a 3-coordinate geometry to three equivalent S(1) atoms. Sn(1) is bonded in a distorted rectangular see-saw-like geometry to two equivalent S(1) and two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(2) is bonded in a 2-coordinate geometry to four equivalent Sn(1) atoms. In the second S site, S(1) is bonded to three equivalent Tl(1) and two equivalent Sn(1) atoms to form a mixture of distorted edge and corner-sharing STl3Sn2 trigonal bipyramids. is represented by the Crystallographic Information File (CIF) [CIF]
