Cr3SnS8 is trigonal omega-derived structured and crystallizes in the monoclinic Cm space group. There are two inequivalent Cr sites. In the first Cr site, Cr(1) is bonded to one S(3), one S(5), two equivalent S(2), and two equivalent S(4) atoms to form CrS6 octahedra that share edges with two equivalent Sn(1)S6 octahedra and edges with four equivalent Cr(2)S6 octahedra. In the second Cr site, Cr(2) is bonded to one S(1), one S(2), one S(3), one S(4), one S(5), and one S(6) atom to form CrS6 octahedra that share edges with two equivalent Cr(1)S6 octahedra, edges with two equivalent Cr(2)S6 octahedra, and edges with two equivalent Sn(1)S6 octahedra. Sn(1) is bonded to one S(1), one S(6), two equivalent S(2), and two equivalent S(4) atoms to form SnS6 octahedra that share edges with two equivalent Cr(1)S6 octahedra and edges with four equivalent Cr(2)S6 octahedra. There are six inequivalent S sites. In the first S site, S(1) is bonded in a distorted T-shaped geometry to two equivalent Cr(2) and one Sn(1) atom. In the second S site, S(2) is bonded in a distorted T-shaped geometry to one Cr(1), one Cr(2), and one Sn(1) atom. In the third S site, S(3) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Cr(2) atoms. In the fourth S site, S(4) is bonded in a distorted T-shaped geometry to one Cr(1), one Cr(2), and one Sn(1) atom. In the fifth S site, S(5) is bonded in a distorted T-shaped geometry to one Cr(1) and two equivalent Cr(2) atoms. In the sixth S site, S(6) is bonded in a distorted T-shaped geometry to two equivalent Cr(2) and one Sn(1) atom.
