Materials Data on VAg3HgO4 by Materials Project
VAg3HgO4 crystallizes in the triclinic P1 space group. The structure is three-dimensional. V3+ is bonded in a tetrahedral geometry to four O2- atoms. All V–O bond lengths are 1.76 Å. There are three inequivalent Ag1+ sites. In the first Ag1+ site, Ag1+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Ag–O bond distances ranging from 2.35–2.47 Å. In the second Ag1+ site, Ag1+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Ag–O bond distances ranging from 2.39–2.43 Å. In the third Ag1+ site, Ag1+ is bonded in a distorted trigonal non-coplanar geometry to three O2- atoms. There are a spread of Ag–O bond distances ranging from 2.32–2.49 Å. Hg2+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Hg–O bond distances ranging from 2.42–2.53 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded to one V3+, two Ag1+, and one Hg2+ atom to form distorted corner-sharing OVAg2Hg tetrahedra. In the second O2- site, O2- is bonded to one V3+, two Ag1+, and one Hg2+ atom to form distorted corner-sharing OVAg2Hg tetrahedra. In the third O2- site, O2- is bonded to one V3+, two Ag1+, and one Hg2+ atom to form distorted corner-sharing OVAg2Hg tetrahedra. In the fourth O2- site, O2- is bonded to one V3+ and three Ag1+ atoms to form distorted corner-sharing OVAg3 tetrahedra.
