Materials Data on Sr3As4 by Materials Project
Abstract
Sr3As4 crystallizes in the orthorhombic Fdd2 space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 8-coordinate geometry to eight As+1.50- atoms. There are a spread of Sr–As bond distances ranging from 3.19–3.35 Å. In the second Sr2+ site, Sr2+ is bonded to eight As+1.50- atoms to form a mixture of distorted edge and corner-sharing SrAs8 hexagonal bipyramids. There are a spread of Sr–As bond distances ranging from 3.18–3.33 Å. There are two inequivalent As+1.50- sites. In the first As+1.50- site, As+1.50- is bonded in a 8-coordinate geometry to six Sr2+ and two As+1.50- atoms. There are one shorter (2.51 Å) and one longer (2.59 Å) As–As bond lengths. In the second As+1.50- site, As+1.50- is bonded in a 7-coordinate geometry to six Sr2+ and one As+1.50- atom.
