Materials Data on CsCa10(PO4)7 by Materials Project
Abstract
CsCa10(PO4)7 crystallizes in the trigonal R3c space group. The structure is three-dimensional. Cs1+ is bonded in a 3-coordinate geometry to nine O2- atoms. There are a spread of Cs–O bond distances ranging from 2.87–3.28 Å. There are four inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 octahedra that share corners with six PO4 tetrahedra. There are three shorter (2.32 Å) and three longer (2.34 Å) Ca–O bond lengths. In the second Ca2+ site, Ca2+ is bonded in a 7-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.35–2.98 Å. In the third Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.37–2.85 Å. In the fourth Ca2+ site, Ca2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ca–O bond distances ranging from 2.42–2.98 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. All P–O bond lengths are 1.56 Å. In the second P5+ site, P5+ is bondedmore »
