Title: Materials Data on Rb5Er(MoO4)4 by Materials Project

Abstract

Rb5Er(MoO4)4 crystallizes in the monoclinic P2/c space group. The structure is three-dimensional. there are three inequivalent Rb1+ sites. In the first Rb1+ site, Rb1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Rb–O bond distances ranging from 2.91–3.00 Å. In the second Rb1+ site, Rb1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.76–3.38 Å. In the third Rb1+ site, Rb1+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Rb–O bond distances ranging from 2.84–3.56 Å. Er3+ is bonded to six O2- atoms to form ErO6 octahedra that share corners with six MoO4 tetrahedra. There are two shorter (2.24 Å) and four longer (2.28 Å) Er–O bond lengths. There are two inequivalent Mo6+ sites. In the first Mo6+ site, Mo6+ is bonded to four O2- atoms to form MoO4 tetrahedra that share corners with two equivalent ErO6 octahedra. The corner-sharing octahedra tilt angles range from 41–46°. There is two shorter (1.77 Å) and two longer (1.83 Å) Mo–O bond length. In the second Mo6+ site, Mo6+ is bonded to four O2- atoms to formmore » MoO4 tetrahedra that share a cornercorner with one ErO6 octahedra. The corner-sharing octahedral tilt angles are 45°. There are a spread of Mo–O bond distances ranging from 1.78–1.86 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Rb1+ and one Mo6+ atom. In the second O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Er3+, and one Mo6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to four Rb1+ and one Mo6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+ and one Mo6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to three Rb1+ and one Mo6+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to three Rb1+, one Er3+, and one Mo6+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to four Rb1+ and one Mo6+ atom. In the eighth O2- site, O2- is bonded in a 2-coordinate geometry to two Rb1+, one Er3+, and one Mo6+ atom.« less
