Materials Data on AgHg2PO4 by Materials Project
AgHg2PO4 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Ag1+ is bonded in a water-like geometry to two equivalent O2- atoms. Both Ag–O bond lengths are 2.34 Å. Hg1+ is bonded in a 3-coordinate geometry to three O2- atoms. There are a spread of Hg–O bond distances ranging from 2.30–2.44 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.55–1.58 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Ag1+, one Hg1+, and one P5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Hg1+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Hg1+ and one P5+ atom.
