Title: Materials Data on SrCa4P3O12F by Materials Project

Abstract

SrCa4P3O12F crystallizes in the hexagonal P6_3 space group. The structure is three-dimensional. Sr2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Sr–O bond distances ranging from 2.53–2.80 Å. There are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to nine O2- atoms. There are a spread of Ca–O bond distances ranging from 2.42–2.91 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- and one F1- atom to form distorted CaO6F pentagonal bipyramids that share corners with six equivalent CaO6F pentagonal bipyramids, corners with four equivalent PO4 tetrahedra, and an edgeedge with one PO4 tetrahedra. There are a spread of Ca–O bond distances ranging from 2.38–2.71 Å. The Ca–F bond length is 2.34 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent CaO6F pentagonal bipyramids and an edgeedge with one CaO6F pentagonal bipyramid. There is two shorter (1.55 Å) and two longer (1.56 Å) P–O bond length. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a 1-coordinate geometry to three Ca2+ and one P5+ atom. In themore » second O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, two Ca2+, and one P5+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, two equivalent Ca2+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Sr2+, two Ca2+, and one P5+ atom. F1- is bonded in a trigonal planar geometry to three equivalent Ca2+ atoms.« less
