Materials Data on CsSm(MoO4)2 by Materials Project

CsSm(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 (3.15 Å) and four longer (3.37 Å) Cs–O bond lengths. Sm3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are four shorter (2.37 Å) and four longer (2.54 Å) Sm–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 1.75–1.87 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Sm3+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Cs1+, one Sm3+, 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.
