Materials Data on Rb2Th(MoO4)3 by Materials Project

Rb2Th(MoO4)3 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.89–3.16 Å. Th4+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Th–O bond distances ranging from 2.34–2.60 Å. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.75 Å) and two longer (1.85 Å) Mo–O bond length. In the second Mo6+ site, Mo6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of Mo–O bond distances ranging from 1.74–1.92 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Rb1+, one Th4+, and one Mo6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Rb1+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Th4+ and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Th4+, and one Mo6+ atom.
