Cu1+ is bonded to five O2- atoms to form distorted CuO5 trigonal bipyramids that share corners with six equivalent LiO4 tetrahedra and edges with two equivalent CuO5 trigonal bipyramids. There are one shorter (2.15 Å) and four longer (2.23 Å) Cu–O bond lengths. There are three inequivalent C4+ sites. In the first C4+ site, C4+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All C–O bond lengths are 1.31 Å. In the second C4+ site, C4+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All C–O bond lengths are 1.30 Å. In the third C4+ site, C4+ is bonded in a trigonal planar geometry to three equivalent O2- atoms. All C–O bond lengths are 1.30 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Cu1+, and one C4+ atom. In the second O2- site, O2- is bonded to two equivalent Li1+, one Cu1+, and one C4+ atom to form distorted corner-sharing OLi2CuC tetrahedra. In the third O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two equivalent Cu1+, and one C4+ atom.
