Materials Data on Mg(AgO2)2 by Materials Project

Abstract

Mg(AgO2)2 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. Mg2+ is bonded in a tetrahedral geometry to four O2- atoms. All Mg–O bond lengths are 2.00 Å. There are three inequivalent Ag3+ sites. In the first Ag3+ site, Ag3+ is bonded in a square co-planar geometry to four O2- atoms. There are two shorter (2.03 Å) and two longer (2.04 Å) Ag–O bond lengths. In the second Ag3+ site, Ag3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Ag–O bond lengths are 2.03 Å. In the third Ag3+ site, Ag3+ is bonded in a square co-planar geometry to four equivalent O2- atoms. All Ag–O bond lengths are 2.03 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mg2+ and two Ag3+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mg2+ and two equivalent Ag3+ atoms. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mg2+ and two equivalent Ag3+ atoms.
