The structure described by K2HgS4 crystallizes in the monoclinic C2/c space group. K(1) is bonded in a 8-coordinate geometry to one Hg(1), three equivalent S(2), and four equivalent S(1) atoms. Hg(1) is bonded in a linear geometry to two equivalent K(1) and two equivalent S(2) atoms. There are two inequivalent S sites. In the first S site, S(1) is bonded in a 5-coordinate geometry to four equivalent K(1) and one S(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 S(1) atom. is represented by the CIF file [CIF]
