Materials Data on Mg2AgWO6 by Materials Project

Abstract

Mg2WAgO6 crystallizes in the monoclinic P2_1/c 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 2.06–2.43 Å. W6+ is bonded in an octahedral geometry to six O2- atoms. There are a spread of W–O bond distances ranging from 1.92–1.99 Å. Ag2+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Ag–O bond distances ranging from 2.04–2.83 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Mg2+, one W6+, and one Ag2+ atom. In the second O2- site, O2- is bonded to two equivalent Mg2+, one W6+, and one Ag2+ atom to form a mixture of distorted edge and corner-sharing OMg2AgW tetrahedra. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Mg2+, one W6+, and one Ag2+ atom.
