Materials Data on SrSO4 by Materials Project

SrSO4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Sr2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Sr–O bond distances ranging from 2.54–3.03 Å. S6+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of S–O bond distances ranging from 1.47–1.50 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Sr2+ and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to one Sr2+ and one S6+ atom. In the third O2- site, O2- is bonded in a distorted single-bond geometry to three equivalent Sr2+ and one S6+ atom.
