Materials Data on Li4Cu(PO3)6 by Materials Project
Li4Cu(PO3)6 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with six PO4 tetrahedra, an edgeedge with one LiO6 octahedra, and an edgeedge with one CuO6 octahedra. There are a spread of Li–O bond distances ranging from 2.10–2.63 Å. In the second Li1+ site, Li1+ is bonded in a 2-coordinate geometry to six O2- atoms. There are a spread of Li–O bond distances ranging from 1.98–2.82 Å. Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with six PO4 tetrahedra and edges with two equivalent LiO6 octahedra. There are a spread of Cu–O bond distances ranging from 1.94–2.40 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 CuO6 octahedra, corners with two equivalent LiO6 octahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 52–63°. 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 CuO6 octahedra, corners with two equivalent LiO6 octahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–69°. There are a spread of P–O bond distances ranging from 1.48–1.62 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share a cornercorner with one CuO6 octahedra, corners with two equivalent LiO6 octahedra, and corners with two PO4 tetrahedra. The corner-sharing octahedra tilt angles range from 57–65°. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu2+, and one P5+ atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms. In the third O2- site, O2- is bonded in a 3-coordinate geometry to three Li1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a distorted single-bond geometry to three Li1+ and one P5+ atom. In the fifth O2- site, O2- is bonded to three Li1+ and one P5+ atom to form distorted edge-sharing OLi3P tetrahedra. In the sixth O2- site, O2- is bonded in a 3-coordinate 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 two P5+ atoms. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu2+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a bent 120 degrees geometry to two P5+ atoms.
