Materials Data on FeAg(MoO4)2 by Materials Project

Abstract

FeAgMo2O8 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.75–2.28 Å. Fe3+ is bonded to six O2- atoms to form edge-sharing FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 1.96–2.17 Å. Ag1+ is bonded to six O2- atoms to form distorted edge-sharing AgO6 octahedra. There are a spread of Ag–O bond distances ranging from 2.39–2.48 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to one Mo6+ and two equivalent Ag1+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Mo6+ and one Ag1+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Mo6+ and one Fe3+ atom. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Mo6+ and two equivalent Fe3+ atoms.
