Materials Data on LiCuPO4 by Materials Project
LiCuPO4 is Chalcostibite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded in a 3-coordinate geometry to five O2- atoms. There are a spread of Li–O bond distances ranging from 1.94–2.74 Å. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 trigonal pyramids that share corners with three CuO5 square pyramids, corners with four PO4 tetrahedra, corners with two equivalent LiO4 trigonal pyramids, and an edgeedge with one CuO5 square pyramid. There are a spread of Li–O bond distances ranging from 2.03–2.22 Å. There are two inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 square pyramids that share corners with two equivalent CuO5 square pyramids, corners with three PO4 tetrahedra, a cornercorner with one LiO4 trigonal pyramid, an edgeedge with one PO4 tetrahedra, and an edgeedge with one LiO4 trigonal pyramid. There are a spread of Cu–O bond distances ranging from 1.93–2.18 Å. In the second Cu2+ site, Cu2+ is bonded to five O2- atoms to form distorted CuO5 square pyramids that share corners with three PO4 tetrahedra, corners with two equivalent LiO4 trigonal pyramids, an edgeedge with one CuO5 square pyramid, and an edgeedge with one PO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.92–2.31 Å. There are two inequivalent P5+ sites. In the first P5+ site, P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with three CuO5 square pyramids, corners with three equivalent LiO4 trigonal pyramids, and an edgeedge with one CuO5 square pyramid. There is two shorter (1.54 Å) and two longer (1.57 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 three CuO5 square pyramids, a cornercorner with one LiO4 trigonal pyramid, and an edgeedge with one CuO5 square pyramid. There are a spread of P–O bond distances ranging from 1.51–1.60 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted trigonal non-coplanar geometry to one Li1+, one Cu2+, and one P5+ atom. In the second O2- site, O2- is bonded to two equivalent Li1+, one Cu2+, and one P5+ atom to form distorted corner-sharing OLi2CuP trigonal pyramids. In the third O2- site, O2- is bonded to one Li1+, two equivalent Cu2+, and one P5+ atom to form distorted OLiCu2P trigonal pyramids that share corners with two equivalent OLi2CuP trigonal pyramids and an edgeedge with one OLiCu2P trigonal pyramid. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Cu2+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a 2-coordinate geometry to one Li1+, one Cu2+, and one P5+ atom. 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 3-coordinate geometry to one Li1+, one Cu2+, and one P5+ atom. In the eighth O2- site, O2- is bonded in a distorted trigonal planar geometry to one Li1+, one Cu2+, and one P5+ atom.
