Materials Data on LiCu4(PO4)3 by Materials Project
LiCu4(PO4)3 crystallizes in the orthorhombic Pnnm space group. The structure is three-dimensional. Li1+ is bonded in a 4-coordinate geometry to four O2- atoms. There are two shorter (2.50 Å) and two longer (2.57 Å) Li–O bond lengths. There are three inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to five O2- atoms to form CuO5 trigonal bipyramids that share corners with two equivalent CuO6 octahedra, corners with five PO4 tetrahedra, and an edgeedge with one CuO5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 61°. There are a spread of Cu–O bond distances ranging from 1.95–2.10 Å. In the second Cu2+ site, Cu2+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 1.87–2.58 Å. In the third Cu2+ site, Cu2+ is bonded to six O2- atoms to form distorted CuO6 octahedra that share corners with four PO4 tetrahedra, a cornercorner with one CuO5 trigonal bipyramid, edges with two equivalent CuO6 octahedra, and an edgeedge with one PO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 2.04–2.55 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 CuO6 octahedra and corners with two equivalent CuO5 trigonal bipyramids. The corner-sharing octahedral tilt angles are 61°. There is one shorter (1.50 Å) and three longer (1.56 Å) P–O bond length. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent CuO6 octahedra and corners with two equivalent CuO5 trigonal bipyramids. The corner-sharing octahedra tilt angles range from 49–56°. There are a spread of P–O bond distances ranging from 1.53–1.63 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with two equivalent CuO6 octahedra, a cornercorner with one CuO5 trigonal bipyramid, and edges with two equivalent CuO6 octahedra. The corner-sharing octahedral tilt angles are 54°. There are a spread of P–O bond distances ranging from 1.53–1.62 Å. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one P5+ atom. In the second O2- site, O2- is bonded in a 4-coordinate geometry to three Cu2+ and one P5+ atom. In the third O2- site, O2- is bonded in a distorted tetrahedral geometry to three Cu2+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a linear geometry to one Cu2+ and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one P5+ atom. In the sixth O2- site, O2- is bonded in a distorted trigonal planar geometry to two equivalent Cu2+ and one P5+ atom. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Cu2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu2+, and one P5+ atom. In the ninth O2- site, O2- is bonded in a 2-coordinate geometry to two Cu2+ and one P5+ atom.
