CsSnS3 crystallizes in the triclinic P-1 space group. Cs(1) is bonded in a 7-coordinate geometry to two equivalent S(2), three equivalent S(1), and three equivalent S(3) atoms. Sn(1) is bonded to one S(1), two equivalent S(2), and two equivalent S(3) atoms to form edge-sharing SnS5 trigonal bipyramids. There are three inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent Cs(1), one Sn(1), and one S(1) atom. In the second S site, S(2) is bonded in a 4-coordinate geometry to two equivalent Cs(1) and two equivalent Sn(1) atoms. In the third S site, S(3) is bonded in a 5-coordinate geometry to three equivalent Cs(1) and two equivalent Sn(1) atoms.
