Cs2Hg3Sn2S8 crystallizes in the triclinic P-1 space group. Cs(1) is bonded in a 10-coordinate geometry to one Hg(1), two equivalent S(1), two equivalent S(3), two equivalent S(4), and three equivalent S(2) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted trigonal planar geometry to one Cs(1), one S(1), one S(2), and one S(4) atom. In the second Hg site, Hg(2) is bonded in a linear geometry to two equivalent S(3) atoms. Sn(1) is bonded in a tetrahedral geometry to one S(1), one S(2), one S(3), and one S(4) atom. There are four inequivalent S sites. In the first S site, S(1) is bonded to two equivalent Cs(1), one Hg(1), and one Sn(1) atom to form distorted edge-sharing SCs2SnHg trigonal pyramids. In the second S site, S(2) is bonded in a 5-coordinate geometry to three equivalent Cs(1), one Hg(1), and one Sn(1) atom. In the third S site, S(3) is bonded in a distorted L-shaped geometry to two equivalent Cs(1), one Hg(2), and one Sn(1) atom. In the fourth S site, S(4) is bonded in a 4-coordinate geometry to two equivalent Cs(1), one Hg(1), and one Sn(1) atom.
