Materials Data on RbEu(MoO4)2 by Materials Project

Abstract

RbEu(MoO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Rb1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Rb–O bond distances ranging from 2.88–3.44 Å. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Eu–O bond distances ranging from 2.37–2.75 Å. Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.78–2.47 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and two equivalent Mo6+ atoms. In the second O2- site, O2- is bonded in a 1-coordinate geometry to one Rb1+, two equivalent Eu3+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Rb1+, one Eu3+, and two equivalent Mo6+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Rb1+, one Eu3+, and one Mo6+ atom.
