Materials Data on Sr3(AsO4)2 by Materials Project
Abstract
Sr3(AsO4)2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 6-coordinate geometry to six equivalent O2- atoms. All Sr–O bond lengths are 2.64 Å. In the second Sr2+ site, Sr2+ is bonded in a 10-coordinate geometry to ten O2- atoms. There are a spread of Sr–O bond distances ranging from 2.40–2.89 Å. As5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.71 Å) and three longer (1.72 Å) As–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted single-bond geometry to four Sr2+ and one As5+ atom. In the second O2- site, O2- is bonded in a linear geometry to one Sr2+ and one As5+ atom.
