title: Materials Data on LiCuBO3 by Materials Project

description: LiCuBO3 crystallizes in the monoclinic Pm space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with six CuO4 tetrahedra and edges with two equivalent LiO5 square pyramids. There are a spread of Li–O bond distances ranging from 2.03–2.14 Å. In the second Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with six CuO4 tetrahedra and edges with two equivalent LiO5 square pyramids. There are a spread of Li–O bond distances ranging from 2.04–2.16 Å. In the third Li1+ site, Li1+ is bonded to five O2- atoms to form distorted LiO5 square pyramids that share corners with six CuO4 tetrahedra and edges with two equivalent LiO5 square pyramids. There are a spread of Li–O bond distances ranging from 2.03–2.15 Å. There are three inequivalent Cu2+ sites. In the first Cu2+ site, Cu2+ is bonded to four O2- atoms to form distorted CuO4 tetrahedra that share corners with six LiO5 square pyramids and corners with two equivalent CuO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.94–2.03 Å. In the second Cu2+ site, Cu2+ is bonded to four O2- atoms to form distorted CuO4 tetrahedra that share corners with six LiO5 square pyramids and corners with two equivalent CuO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.93–2.06 Å. In the third Cu2+ site, Cu2+ is bonded to four O2- atoms to form distorted CuO4 tetrahedra that share corners with six LiO5 square pyramids and corners with two equivalent CuO4 tetrahedra. There are a spread of Cu–O bond distances ranging from 1.94–2.03 Å. There are three inequivalent B3+ sites. In the first B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.37 Å) and two longer (1.39 Å) B–O bond length. In the second B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.38 Å) and one longer (1.39 Å) B–O bond length. In the third B3+ site, B3+ is bonded in a trigonal planar geometry to three O2- atoms. There is one shorter (1.37 Å) and two longer (1.38 Å) B–O bond length. There are nine inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+, one Cu2+, and one B3+ atom to form distorted corner-sharing OLi2CuB tetrahedra. In the second O2- site, O2- is bonded to one Li1+, two equivalent Cu2+, and one B3+ atom to form distorted corner-sharing OLiCu2B tetrahedra. In the third O2- site, O2- is bonded to one Li1+, two equivalent Cu2+, and one B3+ atom to form distorted corner-sharing OLiCu2B tetrahedra. In the fourth O2- site, O2- is bonded to two equivalent Li1+, one Cu2+, and one B3+ atom to form distorted corner-sharing OLi2CuB tetrahedra. In the fifth O2- site, O2- is bonded to one Li1+, two equivalent Cu2+, and one B3+ atom to form distorted corner-sharing OLiCu2B tetrahedra. In the sixth O2- site, O2- is bonded to two equivalent Li1+, one Cu2+, and one B3+ atom to form distorted corner-sharing OLi2CuB tetrahedra. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Cu2+, and one B3+ atom. In the eighth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Cu2+, and one B3+ atom. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent Li1+, one Cu2+, and one B3+ atom.
