Materials Data on SrAsO5 by Materials Project

Abstract

SrAsO5 crystallizes in the orthorhombic Pbca space group. The structure is three-dimensional. Sr is bonded in a 6-coordinate geometry to eight O atoms. There are a spread of Sr–O bond distances ranging from 2.51–3.07 Å. As is bonded in a tetrahedral geometry to four O atoms. There are a spread of As–O bond distances ranging from 1.70–1.75 Å. There are five inequivalent O sites. In the first O site, O is bonded in a distorted bent 150 degrees geometry to one Sr and one As atom. In the second O site, O is bonded in a distorted bent 150 degrees geometry to one Sr and one As atom. In the third O site, O is bonded in a distorted trigonal planar geometry to two equivalent Sr and one As atom. In the fourth O site, O is bonded in a distorted water-like geometry to two equivalent Sr atoms. In the fifth O site, O is bonded in a distorted trigonal planar geometry to two equivalent Sr and one As atom.
