Materials Data on Cu4(PO4)3 by Materials Project

Abstract

Cu4(PO4)3 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are two inequivalent Cu+2.25+ sites. In the first Cu+2.25+ site, Cu+2.25+ is bonded in a rectangular see-saw-like geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.87–1.96 Å. In the second Cu+2.25+ site, Cu+2.25+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.95–2.58 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. In the second P5+ site, P5+ is bonded in a tetrahedral geometry to four O2- atoms. There are a spread of P–O bond distances ranging from 1.52–1.61 Å. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cu+2.25+ and one P5+ atom. In the second O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two Cu+2.25+ and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu+2.25+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a trigonal planar geometry to two equivalent Cu+2.25+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent Cu+2.25+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to one Cu+2.25+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a trigonal planar geometry to two Cu+2.25+ and one P5+ atom.
