Materials Data on CsTm(MoO4)2 by Materials Project

Abstract

CsTm(MoO4)2 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. Cs1+ is bonded in a 4-coordinate geometry to ten O2- atoms. There are a spread of Cs–O bond distances ranging from 3.16–3.71 Å. Tm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.26 Å) and four longer (2.46 Å) Tm–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 four inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Cs1+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+, one Tm3+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Tm3+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 120 degrees geometry to one Cs1+, one Tm3+, and one Mo6+ atom.
