Materials Data on Cs(SO2)2 by Materials Project

Abstract

Cs(SO2)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Cs sites. In the first Cs site, Cs is bonded in a 10-coordinate geometry to two equivalent S and eight O atoms. Both Cs–S bond lengths are 3.84 Å. There are a spread of Cs–O bond distances ranging from 3.13–3.56 Å. In the second Cs site, Cs is bonded in a 10-coordinate geometry to ten O atoms. There are a spread of Cs–O bond distances ranging from 3.13–3.67 Å. There are four inequivalent S sites. In the first S site, S is bonded in a bent 120 degrees geometry to two O atoms. Both S–O bond lengths are 1.46 Å. In the second S site, S is bonded in a trigonal non-coplanar geometry to one S and three O atoms. The S–S bond length is 2.14 Å. There are a spread of S–O bond distances ranging from 1.46–1.48 Å. In the third S site, S is bonded in a 4-coordinate geometry to two equivalent Cs and two S atoms. The S–S bond length is 2.16 Å. In the fourth S site, S is bonded in a trigonal non-coplanar geometry to one S and three O atoms. There is one shorter (1.46 Å) and two longer (1.47 Å) S–O bond length. There are eight inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to two Cs and one S atom. In the second O site, O is bonded in a single-bond geometry to one Cs and one S atom. In the third O site, O is bonded in a distorted single-bond geometry to three Cs and one S atom. In the fourth O site, O is bonded in a distorted single-bond geometry to two equivalent Cs and one S atom. In the fifth O site, O is bonded in a distorted single-bond geometry to three Cs and one S atom. In the sixth O site, O is bonded in a distorted single-bond geometry to two equivalent Cs and one S atom. In the seventh O site, O is bonded in a single-bond geometry to three Cs and one S atom. In the eighth O site, O is bonded in a single-bond geometry to two Cs and one S atom.
