Materials Data on Li2Cu(PO3)4 by Materials Project
Li2Cu(PO3)4 crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Li1+ is bonded in a distorted rectangular see-saw-like geometry to four O2- atoms. There are a spread of Li–O bond distances ranging from 2.00–2.07 Å. Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with six PO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.91–2.41 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 CuO6 octahedra and corners with two equivalent PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 9–50°. There are a spread of P–O bond distances ranging from 1.49–1.59 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CuO6 octahedra and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 46–50°. There are a spread of P–O bond distances ranging from 1.50–1.61 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.61 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Cu2+, and one P5+ atom. In the second O2- site, O2- is bonded in a linear geometry to one Cu2+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a bent 150 degrees geometry to two P5+ atoms. In the fifth O2- site, O2- is bonded in a distorted bent 150 degrees geometry to two P5+ atoms. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a bent 120 degrees geometry to one Cu2+ and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted T-shaped geometry to two equivalent Li1+ and one P5+ atom.
