Materials Data on CsLa(SO4)2 by Materials Project
CsLa(SO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Cs1+ is bonded in a 12-coordinate geometry to thirteen O2- atoms. There are a spread of Cs–O bond distances ranging from 3.24–3.67 Å. La3+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of La–O bond distances ranging from 2.50–2.82 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.48–1.51 Å. In the second S6+ site, S6+ is bonded in a tetrahedral geometry to four O2- atoms. There is two shorter (1.49 Å) and two longer (1.50 Å) S–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+, one La3+, and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+, one La3+, and one S6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+, one La3+, and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+, one La3+, and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cs1+, one La3+, and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to one Cs1+, one La3+, and one S6+ atom. In the seventh O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Cs1+, one La3+, and one S6+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent La3+ and one S6+ atom.
