Materials Data on Sr10P6SO24 by Materials Project

Sr10P6SO24 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to one S2- and six O2- atoms. The Sr–S bond length is 3.05 Å. There are a spread of Sr–O bond distances ranging from 2.51–2.82 Å. In the second Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.63–2.77 Å. In the third Sr2+ site, Sr2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are three shorter (2.52 Å) and three longer (2.54 Å) Sr–O bond lengths. P5+ is bonded in a tetrahedral geometry to four O2- atoms. All P–O bond lengths are 1.56 Å. S2- is bonded in a distorted octahedral geometry to six equivalent Sr2+ atoms. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three Sr2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to three Sr2+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Sr2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to three Sr2+ and one P5+ atom.
