Title: Materials Data on Ca3(PO4)2 by Materials Project

Abstract

Ca3(PO4)2 crystallizes in the trigonal R-3m space group. The structure is three-dimensional. there are two inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 12-coordinate geometry to six equivalent O2- atoms. All Ca–O bond lengths are 2.46 Å. In the second Ca2+ site, Ca2+ is bonded in a 1-coordinate geometry to ten O2- atoms. There are a spread of Ca–O bond distances ranging from 2.24–2.72 Å. P5+ is bonded in a tetrahedral geometry to four O2- atoms. There is one shorter (1.54 Å) and three longer (1.56 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a linear geometry to one Ca2+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to four Ca2+ and one P5+ atom.
