Materials Data on CsEu(MoO4)2 by Materials Project

Abstract

CsEu(MoO4)2 crystallizes in the orthorhombic Pccm space group. The structure is three-dimensional. Cs1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (3.12 Å) and four longer (3.34 Å) Cs–O bond lengths. Eu3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.42 Å) and four longer (2.55 Å) Eu–O bond lengths. Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mo–O bond distances ranging from 1.75–1.86 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Eu3+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Eu3+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+ and one Mo6+ atom.
