Materials Data on Mg2Ag2O5 by Materials Project

Abstract

Mg2Ag2O5 crystallizes in the orthorhombic Pbam space group. The structure is three-dimensional. Mg2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mg–O bond distances ranging from 2.14–2.43 Å. Ag3+ is bonded to five O2- atoms to form distorted corner-sharing AgO5 square pyramids. There are a spread of Ag–O bond distances ranging from 2.06–2.38 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to four equivalent Mg2+ and two equivalent Ag3+ atoms. In the second O2- site, O2- is bonded to two equivalent Mg2+ and two equivalent Ag3+ atoms to form distorted corner-sharing OMg2Ag2 tetrahedra. In the third O2- site, O2- is bonded to two equivalent Mg2+ and two equivalent Ag3+ atoms to form a mixture of distorted corner and edge-sharing OMg2Ag2 trigonal pyramids.
