In the sixth Ni+3.54+ site, Ni+3.54+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with six LiO6 octahedra, edges with two equivalent LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedra tilt angles range from 10–13°. There are a spread of Ni–O bond distances ranging from 1.87–2.05 Å. In the seventh Ni+3.54+ site, Ni+3.54+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with three LiO6 octahedra, edges with three LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedra tilt angles range from 11–16°. There are a spread of Ni–O bond distances ranging from 1.88–2.00 Å. There are thirteen inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Ni+3.54+ atoms. In the second O2- site, O2- is bonded to two equivalent Li1+ and three Ni+3.54+ atoms to form a mixture of corner and edge-sharing OLi2Ni3 square pyramids.
