Materials Data on K2Hg3(GeS4)2 by Materials Project
K2Hg3(GeS4)2 crystallizes in the orthorhombic Aea2 space group. The structure is three-dimensional. K1+ is bonded in a 7-coordinate geometry to seven S2- atoms. There are a spread of K–S bond distances ranging from 3.27–3.57 Å. There are two inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a see-saw-like geometry to four S2- atoms. There are a spread of Hg–S bond distances ranging from 2.46–2.92 Å. In the second Hg2+ site, Hg2+ is bonded in a distorted linear geometry to four S2- atoms. There are two shorter (2.38 Å) and two longer (3.35 Å) Hg–S bond lengths. Ge4+ is bonded in a tetrahedral geometry to four S2- atoms. There are a spread of Ge–S bond distances ranging from 2.19–2.28 Å. There are four inequivalent S2- sites. In the first S2- site, S2- is bonded in a 2-coordinate geometry to two equivalent K1+, one Hg2+, and one Ge4+ atom. In the second S2- site, S2- is bonded in a 4-coordinate geometry to two equivalent K1+, one Hg2+, and one Ge4+ atom. In the third S2- site, S2- is bonded in a 4-coordinate geometry to one K1+, two equivalent Hg2+, and one Ge4+ atom. In the fourth S2- site, S2- is bonded in a 5-coordinate geometry to two equivalent K1+, two Hg2+, and one Ge4+ atom.
