The structure described by K2Hg3(GeS4)2 crystallizes in the orthorhombic Aea2 space group. K(1) is bonded in a 7-coordinate geometry to one S(4), two equivalent S(1), two equivalent S(2), and two equivalent S(3) atoms. There are two inequivalent Hg sites. In the first Hg site, Hg(1) is bonded in a distorted see-saw-like geometry to one S(1), one S(2), and two equivalent S(4) atoms. In the second Hg site, Hg(2) is bonded in a linear geometry to two equivalent S(3) atoms. Ge(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(2) is bonded to two equivalent K(1), one Hg(1), and one Ge(1) atom to form distorted corner-sharing SK2HgGe trigonal pyramids. In the second S site, S(3) is bonded to two equivalent K(1), one Hg(2), and one Ge(1) atom to form distorted corner-sharing SK2HgGe trigonal pyramids. In the third S site, S(4) is bonded in a 4-coordinate geometry to one K(1), two equivalent Hg(1), and one Ge(1) atom. In the fourth S site, S(1) is bonded in a 4-coordinate geometry to two equivalent K(1), one Hg(1), and one Ge(1) atom. is represented by the CIF card [CIF]
