Materials Data on Li2Cu(PO3)3 by Materials Project

Abstract

Li2Cu(PO3)3 crystallizes in the orthorhombic P2_12_12_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 1.94–2.60 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with six PO4 tetrahedra and edges with three equivalent CuO6 octahedra. There are a spread of Li–O bond distances ranging from 1.96–2.54 Å. Cu1+ is bonded to six O2- atoms to form CuO6 octahedra that share corners with six PO4 tetrahedra and edges with three equivalent LiO6 octahedra. There are a spread of Cu–O bond distances ranging from 2.15–2.55 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 corners with two equivalent LiO6 octahedra, corners with two equivalent CuO6 octahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 52–55°. There are a spread of P–O bond distances ranging from 1.49–1.65 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent LiO6 octahedra, corners with two equivalent CuO6 octahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 51–64°. There are a spread of P–O bond distances ranging from 1.50–1.63 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent LiO6 octahedra, corners with two equivalent CuO6 octahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 23–58°. There are a spread of P–O bond distances ranging from 1.49–1.66 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+ and two P5+ atoms. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+ and two P5+ atoms. In the third O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Cu1+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Cu1+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu1+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 2-coordinate geometry to two Li1+, one Cu1+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+ and two P5+ atoms. In the eighth O2- site, O2- is bonded in a 1-coordinate geometry to two Li1+, one Cu1+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu1+, and one P5+ atom.
