Materials Data on Li2CuP3(HO5)2 by Materials Project

Abstract

Li2CuP3(HO5)2 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 2.11–2.77 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 trigonal bipyramids that share corners with two equivalent CuO4 tetrahedra and corners with five PO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.04–2.36 Å. Cu1+ is bonded to four O2- atoms to form distorted CuO4 tetrahedra that share corners with three PO4 tetrahedra and corners with two equivalent LiO5 trigonal bipyramids. There are a spread of Cu–O bond distances ranging from 2.01–2.20 Å. There are three inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CuO4 tetrahedra, corners with two PO4 tetrahedra, and a cornercorner with one LiO5 trigonal bipyramid. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CuO4 tetrahedra, corners with two PO4 tetrahedra, and corners with two equivalent LiO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.51–1.61 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CuO4 tetrahedra, corners with two PO4 tetrahedra, and corners with two equivalent LiO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to two O2- atoms. There is one shorter (0.99 Å) and one longer (1.74 Å) H–O bond length. In the second H1+ site, H1+ is bonded in a single-bond geometry to one O2- atom. The H–O bond length is 0.99 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one Li1+, one Cu1+, and two H1+ atoms. In the second O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu1+, and one P5+ atom. In the third O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Li1+, one P5+, and one H1+ atom. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to three Li1+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the seventh O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu1+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a 1-coordinate geometry to two Li1+ and one P5+ atom. In the tenth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu1+, and one P5+ atom.
