title: Materials Data on Cu9P4(HO10)2 by Materials Project

description: Cu9P4(HO10)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are five inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a square co-planar geometry to four O2- atoms. There is two shorter (1.93 Å) and two longer (1.95 Å) Cu–O bond length. In the second Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 trigonal bipyramids that share corners with two equivalent CuO5 square pyramids, corners with four PO4 tetrahedra, corners with two CuO5 trigonal bipyramids, and an edgeedge with one CuO5 trigonal bipyramid. There are a spread of Cu–O bond distances ranging from 1.94–2.38 Å. In the third Cu2+ site, Cu2+ is bonded to five O2- atoms to form CuO5 trigonal bipyramids that share a cornercorner with one CuO5 square pyramid, corners with three PO4 tetrahedra, corners with two CuO5 trigonal bipyramids, and edges with two CuO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.94–2.20 Å. In the fourth 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 three PO4 tetrahedra, corners with two CuO5 trigonal bipyramids, and an edgeedge with one CuO5 trigonal bipyramid. There are a spread of Cu–O bond distances ranging from 1.95–2.26 Å. In the fifth Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 square pyramids that share corners with four PO4 tetrahedra and corners with five CuO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 1.95–2.40 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent CuO5 square pyramids and corners with four CuO5 trigonal bipyramids. There is one shorter (1.55 Å) and three longer (1.56 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CuO5 square pyramid and corners with six CuO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (1.01 Å) and one longer (1.69 Å) H–O bond length. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Cu2+, one P5+, and one H1+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to three Cu2+ and one H1+ atom. In the third O2- site, O2- is bonded to four Cu2+ atoms to form corner-sharing OCu4 tetrahedra. In the fourth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cu2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a 3-coordinate geometry to two Cu2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to two Cu2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to two Cu2+ and one P5+ atom. In the ninth O2- site, O2- is bonded in a trigonal planar geometry to two Cu2+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Cu2+ and one P5+ atom.
