Materials Data on SrP3 by Materials Project

Abstract

SrP3 crystallizes in the monoclinic C2/m space group. The structure is three-dimensional. there are two inequivalent Sr2+ sites. In the first Sr2+ site, Sr2+ is bonded in a 9-coordinate geometry to nine P+0.67- atoms. There are a spread of Sr–P bond distances ranging from 3.08–3.46 Å. In the second Sr2+ site, Sr2+ is bonded in a 7-coordinate geometry to eight P+0.67- atoms. There are a spread of Sr–P bond distances ranging from 3.07–3.46 Å. There are four inequivalent P+0.67- sites. In the first P+0.67- site, P+0.67- is bonded in a 6-coordinate geometry to four Sr2+ and two P+0.67- atoms. There are one shorter (2.19 Å) and one longer (2.20 Å) P–P bond lengths. In the second P+0.67- site, P+0.67- is bonded in a 5-coordinate geometry to three Sr2+ and two P+0.67- atoms. There are one shorter (2.21 Å) and one longer (2.24 Å) P–P bond lengths. In the third P+0.67- site, P+0.67- is bonded in a 4-coordinate geometry to two Sr2+ and three P+0.67- atoms. The P–P bond length is 2.25 Å. In the fourth P+0.67- site, P+0.67- is bonded in a distorted tetrahedral geometry to one Sr2+ and three P+0.67- atoms.
