Materials Data on LiCu(PO3)2 by Materials Project

Abstract

LiCu(PO3)2 crystallizes in the orthorhombic C222 space group. The structure is three-dimensional. Li1+ is bonded to four equivalent O2- atoms to form LiO4 tetrahedra that share corners with four equivalent PO4 tetrahedra and edges with two equivalent CuO4 tetrahedra. All Li–O bond lengths are 1.91 Å. Cu1+ is bonded to four equivalent O2- atoms to form distorted CuO4 tetrahedra that share corners with four equivalent PO4 tetrahedra and edges with two equivalent LiO4 tetrahedra. All Cu–O bond lengths are 2.06 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent LiO4 tetrahedra, corners with two equivalent CuO4 tetrahedra, and corners with two equivalent PO4 tetrahedra. There is two shorter (1.50 Å) and two longer (1.60 Å) P–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu1+, and one P5+ atom. In the second O2- site, O2- is bonded in a linear geometry to two equivalent P5+ atoms.
