Materials Data on LiCuPO4 by Materials Project
LiCuPO4 is Chalcostibite-derived structured and crystallizes in the orthorhombic Pna2_1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share a cornercorner with one LiO5 square pyramid, corners with six PO4 tetrahedra, and an edgeedge with one LiO5 square pyramid. There are a spread of Li–O bond distances ranging from 2.04–2.54 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share a cornercorner with one LiO6 octahedra, a cornercorner with one LiO5 square pyramid, corners with five PO4 tetrahedra, corners with two equivalent CuO5 trigonal bipyramids, and an edgeedge with one CuO5 trigonal bipyramid. The corner-sharing octahedral tilt angles are 76°. There are a spread of Li–O bond distances ranging from 1.97–2.38 Å. In the third Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share a cornercorner with one LiO5 square pyramid, corners with five PO4 tetrahedra, an edgeedge with one LiO6 octahedra, and an edgeedge with one CuO5 trigonal bipyramid. There are a spread of Li–O bond distances ranging from 1.95–2.21 Å. There are three inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.91–2.05 Å. In the second Cu2+ site, Cu2+ is bonded in a 4-coordinate geometry to four O2- atoms. There are a spread of Cu–O bond distances ranging from 1.92–2.12 Å. In the third Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 trigonal bipyramids that share corners with two equivalent LiO5 square pyramids, corners with five PO4 tetrahedra, and edges with two LiO5 square pyramids. There are a spread of Cu–O bond distances ranging from 1.95–2.34 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 three equivalent LiO6 octahedra, corners with two LiO5 square pyramids, and a cornercorner with one CuO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 57–67°. There are a spread of P–O bond distances ranging from 1.53–1.59 Å. In the second P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three equivalent LiO6 octahedra, corners with three LiO5 square pyramids, and a cornercorner with one CuO5 trigonal bipyramid. The corner-sharing octahedra tilt angles range from 32–56°. There are a spread of P–O bond distances ranging from 1.53–1.57 Å. In the third P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with five LiO5 square pyramids and corners with three equivalent CuO5 trigonal bipyramids. There are a spread of P–O bond distances ranging from 1.53–1.58 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu2+, and one P5+ atom. In the second O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu2+, and one P5+ atom. In the third O2- site, O2- is bonded in a 3-coordinate geometry to two Li1+ and one P5+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to two Li1+, one Cu2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 3-coordinate geometry to one Li1+, one Cu2+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Cu2+, and one P5+ atom. In the seventh O2- site, O2- is bonded in a distorted tetrahedral 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 3-coordinate geometry to one Li1+, one Cu2+, and one P5+ atom. In the tenth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Cu2+, and one P5+ atom. In the eleventh O2- site, O2- is bonded in a 4-coordinate geometry to two Li1+, one Cu2+, and one P5+ atom. In the twelfth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu2+, and one P5+ atom.
