K2Hg3S4 crystallizes in the orthorhombic Pbcn space group. K(1) is bonded in a 6-coordinate geometry to three equivalent S(1) and three equivalent S(2) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a tetrahedral geometry to two equivalent S(1) and two equivalent S(2) atoms. In the second Hg site, Hg(2) is bonded in a distorted linear geometry to one S(1) and one S(2) atom. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent K(1), one Hg(1), and one Hg(2) atom. In the second S site, S(2) is bonded in a 5-coordinate geometry to three equivalent K(1), one Hg(1), and one Hg(2) atom.
K2Hg3S4 crystallizes in the orthorhombic Pbcn space group. K(1) is bonded in a 6-coordinate geometry to three equivalent S(1) and three equivalent S(2) atoms. There are a spread of K(1)-S(1) bond distances ranging from 3.30-3.35 Å. There is one shorter (3.23 Å) and two longer (3.31 Å) K(1)-S(2) bond lengths. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a tetrahedral geometry to two equivalent S(1) and two equivalent S(2) atoms. Both Hg(1)-S(1) bond lengths are 2.62 Å. Both Hg(1)-S(2) bond lengths are 2.60 Å. In the second Hg site, Hg(2) is bonded in a distorted linear geometry to one S(1) and one S(2) atom. The Hg(2)-S(1) bond length is 2.38 Å. The Hg(2)-S(2) bond length is 2.39 Å. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to three equivalent K(1), one Hg(1), and one Hg(2) atom. In the second S site, S(2) is bonded in a 5-coordinate geometry to three equivalent K(1), one Hg(1), and one Hg(2) atom.
