Materials Data on Li2CuPCO7 by Materials Project
Li2CuCPO7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with two equivalent CuO6 octahedra, corners with three equivalent PO4 tetrahedra, an edgeedge with one LiO6 octahedra, a faceface with one LiO6 octahedra, and a faceface with one CuO6 octahedra. The corner-sharing octahedra tilt angles range from 65–79°. There are a spread of Li–O bond distances ranging from 2.03–2.43 Å. Cu3+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four equivalent LiO6 octahedra, corners with four equivalent PO4 tetrahedra, and faces with two equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 65–79°. There are a spread of Cu–O bond distances ranging from 1.95–2.12 Å. C4+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.26–1.31 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent CuO6 octahedra and corners with six equivalent LiO6 octahedra. The corner-sharing octahedra tilt angles range from 46–69°. There is three shorter (1.55 Å) and one longer (1.56 Å) P–O bond length. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li1+, one Cu3+, and one C4+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Li1+, one Cu3+, and one C4+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu3+, and one P5+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Cu3+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted tetrahedral geometry to two equivalent Li1+, one Cu3+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Li1+ and one C4+ atom.
