In the second K site, K(2) is bonded in a 3-coordinate geometry to one O(1), two equivalent O(2), and one Cl(4) atom. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a 5-coordinate geometry to one S(1), one Cl(2), and three equivalent Cl(1) atoms. In the second Hg site, Hg(2) is bonded in a distorted linear geometry to one Cl(3), one Cl(4), and three equivalent Cl(2) atoms. S(1) is bonded in a distorted trigonal non-coplanar geometry to one Hg(1), one O(1), and two equivalent O(2) atoms. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted linear geometry to one K(2) and one S(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one S(1) atom. There are four inequivalent Cl sites. In the first Cl site, Cl(1) is bonded in a 4-coordinate geometry to one K(1) and three equivalent Hg(1) atoms. In the second Cl site, Cl(2) is bonded to one K(1), one Hg(1), and three equivalent Hg(2) atoms to form distorted ClKHg4 square pyramids that share corners with two equivalent Cl(2)KHg4 square pyramids,  a cornercorner with one Cl(4)K3Hg tetrahedra, edges with two equivalent Cl(2)KHg4 square pyramids, and edges with two equivalent Cl(4)K3Hg tetrahedra. In the third Cl site, Cl(3) is bonded in a distorted single-bond geometry to one K(1) and one Hg(2) atom. In the fourth Cl site, Cl(4) is bonded to one K(2), two equivalent K(1), and one Hg(2) atom to form distorted ClK3Hg tetrahedra that share  a cornercorner with one Cl(2)KHg4 square pyramid, corners with two equivalent Cl(4)K3Hg tetrahedra, and edges with two equivalent Cl(2)KHg4 square pyramids. is represented by the CIF file [CIF]
