Materials Data on Sr3(AsO4)2 by Materials Project
Sr3(AsO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.47–2.90 Å. In the second Sr2+ site, Sr2+ is bonded in a 5-coordinate geometry to six O2- atoms. There are a spread of Sr–O bond distances ranging from 2.46–3.12 Å. In the third Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of Sr–O bond distances ranging from 2.45–3.05 Å. There are two inequivalent As5+ sites. In the first As5+ site, As5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.71 Å) and three longer (1.73 Å) As–O bond length. In the second As5+ site, As5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.72 Å) and three longer (1.73 Å) As–O bond length. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Sr2+ and one As5+ atom. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Sr2+ and one As5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to three Sr2+ and one As5+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Sr2+ and one As5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to two Sr2+ and one As5+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to three Sr2+ and one As5+ atom. In the seventh O2- site, O2- is bonded in a 2-coordinate geometry to three Sr2+ and one As5+ atom. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to three Sr2+ and one As5+ atom.
