Materials Data on AgHgO2 by Materials Project

Abstract

AgHgO2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Ag2+ sites. In the first Ag2+ site, Ag2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.16 Å) and two longer (2.18 Å) Ag–O bond lengths. In the second Ag2+ site, Ag2+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.15 Å) and two longer (2.16 Å) Ag–O bond lengths. There are two inequivalent Hg2+ sites. In the first Hg2+ site, Hg2+ is bonded in a 2-coordinate geometry to four O2- atoms. There are two shorter (2.08 Å) and two longer (2.72 Å) Hg–O bond lengths. In the second Hg2+ site, Hg2+ is bonded in a distorted linear geometry to four O2- atoms. There are two shorter (2.07 Å) and two longer (2.77 Å) Hg–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to two Ag2+ and two Hg2+ atoms to form a mixture of distorted corner and edge-sharing OAg2Hg2 tetrahedra. In the second O2- site, O2- is bonded to two Ag2+ and two Hg2+ atoms to form a mixture of distorted corner and edge-sharing OAg2Hg2 tetrahedra.
