Materials Data on CaS3O10 by Materials Project
CaS3O10 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.42–2.75 Å. There are three inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.43–1.58 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There are a spread of S–O bond distances ranging from 1.44–1.75 Å. In the third S6+ site, S6+ is bonded to four O2- atoms to form corner-sharing SO4 tetrahedra. There is three shorter (1.44 Å) and one longer (1.74 Å) S–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a bent 120 degrees geometry to two S6+ atoms. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two S6+ atoms. In the third O2- site, O2- is bonded in a distorted linear geometry to one Ca2+ and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ca2+ and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ca2+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ca2+ and one S6+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to one Ca2+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a distorted linear geometry to one Ca2+ and one S6+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to one Ca2+ and one S6+ atom. In the tenth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Ca2+ and one S6+ atom.
