Li3(NiO2)5 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six NiO6 octahedra, edges with three LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedra tilt angles range from 9–14°. There are a spread of Li–O bond distances ranging from 2.05–2.19 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form LiO6 octahedra that share corners with six NiO6 octahedra, edges with two equivalent LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedra tilt angles range from 10–14°. There are a spread of Li–O bond distances ranging from 2.05–2.15 Å. There are three inequivalent Ni+3.40+ sites. In the first Ni+3.40+ site, Ni+3.40+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with five LiO6 octahedra, edges with three LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedra tilt angles range from 10–14°. There are a spread of Ni–O bond distances ranging from 1.94–2.08 Å. In the second Ni+3.40+ site, Ni+3.40+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with three LiO6 octahedra, edges with four LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedra tilt angles range from 9–10°. There is three shorter (1.87 Å) and three longer (1.91 Å) Ni–O bond length. In the third Ni+3.40+ site, Ni+3.40+ is bonded to six O2- atoms to form NiO6 octahedra that share corners with two equivalent LiO6 octahedra, edges with four LiO6 octahedra, and edges with six NiO6 octahedra. The corner-sharing octahedral tilt angles are 9°. There are a spread of Ni–O bond distances ranging from 1.85–1.90 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded to two equivalent Li1+ and three Ni+3.40+ atoms to form a mixture of edge and corner-sharing OLi2Ni3 square pyramids. In the second O2- site, O2- is bonded to two Li1+ and three Ni+3.40+ atoms to form a mixture of edge and corner-sharing OLi2Ni3 square pyramids. In the third O2- site, O2- is bonded to two equivalent Li1+ and three Ni+3.40+ atoms to form a mixture of edge and corner-sharing OLi2Ni3 square pyramids. In the fourth O2- site, O2- is bonded in a rectangular see-saw-like geometry to one Li1+ and three Ni+3.40+ atoms. In the fifth O2- site, O2- is bonded to two Li1+ and three Ni+3.40+ atoms to form a mixture of edge and corner-sharing OLi2Ni3 square pyramids.
