Materials Data on Sr5P3O14 by Materials Project
Sr5P3O14 crystallizes in the hexagonal P6_3/m space group. The structure is three-dimensional. there are two inequivalent Sr sites. In the first Sr site, Sr is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Sr–O bond distances ranging from 2.59–2.94 Å. In the second Sr site, Sr is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of Sr–O bond distances ranging from 2.50–2.83 Å. P is bonded in a tetrahedral geometry to four O atoms. All P–O bond lengths are 1.56 Å. There are four inequivalent O sites. In the first O site, O is bonded to three equivalent Sr and one O atom to form face-sharing OSr3O tetrahedra. The O–O bond length is 1.35 Å. In the second O site, O is bonded in a distorted single-bond geometry to three Sr and one P atom. In the third O site, O is bonded in a 1-coordinate geometry to three Sr and one P atom. In the fourth O site, O is bonded in a 4-coordinate geometry to three Sr and one P atom.
