Title: Materials Data on Cu4P2O9 by Materials Project

Abstract

Cu4O(PO4)2 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. there are three inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to five O2- atoms to form CuO5 trigonal bipyramids that share corners with two equivalent CuO5 square pyramids, corners with four PO4 tetrahedra, edges with two equivalent CuO5 square pyramids, and an edgeedge with one CuO5 trigonal bipyramid. There are a spread of Cu–O bond distances ranging from 1.95–2.28 Å. In the second Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 trigonal bipyramids that share corners with four PO4 tetrahedra, edges with two equivalent CuO5 square pyramids, and an edgeedge with one CuO5 trigonal bipyramid. There are a spread of Cu–O bond distances ranging from 1.86–2.20 Å. In the third Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 square pyramids that share a cornercorner with one CuO5 square pyramid, corners with four PO4 tetrahedra, a cornercorner with one CuO5 trigonal bipyramid, an edgeedge with one CuO5 square pyramid, and edges with two CuO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.91–2.43 Å. There are two inequivalent P5+ sites. Inmore » the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent CuO5 square pyramids and corners with four CuO5 trigonal bipyramids. There is one shorter (1.51 Å) and three longer (1.57 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent CuO5 square pyramids and corners with four CuO5 trigonal bipyramids. There is three shorter (1.55 Å) and one longer (1.58 Å) P–O bond length. There are seven inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to two Cu2+ and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Cu2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to one Cu2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Cu2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a tetrahedral geometry to four Cu2+ atoms. In the seventh O2- site, O2- is bonded in a 3-coordinate geometry to two Cu2+ and one P5+ atom.« less
