Abstract

Rb3Tm(SO4)3 crystallizes in the monoclinic Cc 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 eight O2- atoms. There are a spread of Rb–O bond distances ranging from 2.82–3.47 Å. In the second Rb1+ site, Rb1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Rb–O bond distances ranging from 2.87–3.24 Å. In the third 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 2.92–3.38 Å. Tm3+ is bonded to seven O2- atoms to form TmO7 pentagonal bipyramids that share corners with five SO4 tetrahedra and an edgeedge with one SO4 tetrahedra. There are a spread of Tm–O bond distances ranging from 2.19–2.49 Å. There are three inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent TmO7 pentagonal bipyramids. There are a spread of S–O bond distances ranging from 1.47–1.51 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share a cornercorner with one TmO7 pentagonal bipyramid and an edgeedge with one TmO7 pentagonal bipyramid. There are a spread of S–O bond distances ranging from 1.47–1.51 Å. In the third S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent TmO7 pentagonal bipyramids. There are a spread of S–O bond distances ranging from 1.47–1.52 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted linear geometry to one Tm3+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Rb1+, one Tm3+, and one S6+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to one Rb1+, one Tm3+, and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two Rb1+, one Tm3+, and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Rb1+, one Tm3+, and one S6+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one S6+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two Rb1+, one Tm3+, and one S6+ atom. In the eleventh O2- site, O2- is bonded in a 2-coordinate geometry to one Rb1+, one Tm3+, and one S6+ atom. In the twelfth O2- site, O2- is bonded in a distorted single-bond geometry to three Rb1+ and one S6+ atom.
