Materials Data on CsEr(MoO4)2 by Materials Project

Abstract

CsEr(MoO4)2 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Cs1+ is bonded in a 12-coordinate geometry to twelve O2- atoms. There are a spread of Cs–O bond distances ranging from 2.90–3.41 Å. Er3+ is bonded in a 6-coordinate geometry to eight O2- atoms. There are a spread of Er–O bond distances ranging from 2.30–2.75 Å. Mo6+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mo–O bond distances ranging from 1.78–2.39 Å. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and two equivalent Mo6+ atoms. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, two equivalent Er3+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Cs1+, one Er3+, and two equivalent Mo6+ atoms. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to two equivalent Cs1+, one Er3+, and one Mo6+ atom.
