Materials Data on SrPSe3 by Materials Project
SrPSe3 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight Se2- atoms. There are a spread of Sr–Se bond distances ranging from 3.21–3.39 Å. P4+ is bonded in a trigonal non-coplanar geometry to three Se2- atoms. There are a spread of P–Se bond distances ranging from 2.20–2.22 Å. There are three inequivalent Se2- sites. In the first Se2- site, Se2- is bonded in a 3-coordinate geometry to two equivalent Sr2+ and one P4+ atom. In the second Se2- site, Se2- is bonded in a 4-coordinate geometry to three equivalent Sr2+ and one P4+ atom. In the third Se2- site, Se2- is bonded in a 4-coordinate geometry to three equivalent Sr2+ and one P4+ atom.
