Li3Nb4CuO12 is Ilmenite-derived structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are three inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with three NbO6 octahedra, edges with three NbO6 octahedra, and a faceface with one NbO6 octahedra. The corner-sharing octahedra tilt angles range from 57–61°. There are a spread of Li–O bond distances ranging from 2.09–2.26 Å. In the second Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with three NbO6 octahedra, corners with four equivalent LiO6 octahedra, edges with three NbO6 octahedra, and a faceface with one NbO6 octahedra. The corner-sharing octahedra tilt angles range from 56–62°. There are a spread of Li–O bond distances ranging from 2.08–2.25 Å. In the third Li1+ site, Li1+ is bonded to six O2- atoms to form distorted LiO6 octahedra that share corners with three NbO6 octahedra, corners with six LiO6 octahedra, edges with three NbO6 octahedra, and a faceface with one NbO6 octahedra. The corner-sharing octahedra tilt angles range from 56–62°. There are a spread of Li–O bond distances ranging from 2.10–2.26 Å. There are four inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to six O2- atoms to form NbO6 octahedra that share corners with two equivalent LiO6 octahedra, corners with six NbO6 octahedra, and edges with three LiO6 octahedra. The corner-sharing octahedra tilt angles range from 40–62°. There are a spread of Nb–O bond distances ranging from 1.90–2.19 Å. In the second Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted NbO6 octahedra that share a cornercorner with one LiO6 octahedra, corners with six NbO6 octahedra, edges with three LiO6 octahedra, and a faceface with one LiO6 octahedra. The corner-sharing octahedra tilt angles range from 39–62°. There are a spread of Nb–O bond distances ranging from 1.90–2.19 Å. In the third Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted NbO6 octahedra that share corners with three LiO6 octahedra, corners with six NbO6 octahedra, edges with two equivalent LiO6 octahedra, and a faceface with one LiO6 octahedra. The corner-sharing octahedra tilt angles range from 39–62°. There are a spread of Nb–O bond distances ranging from 1.90–2.20 Å. In the fourth Nb5+ site, Nb5+ is bonded to six O2- atoms to form distorted NbO6 octahedra that share corners with three LiO6 octahedra, corners with six NbO6 octahedra, an edgeedge with one LiO6 octahedra, and a faceface with one LiO6 octahedra. The corner-sharing octahedra tilt angles range from 39–60°. There are a spread of Nb–O bond distances ranging from 1.90–2.21 Å. Cu1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Cu–O bond distances ranging from 2.08–2.42 Å. There are twelve inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+ and two Nb5+ atoms. In the second O2- site, O2- is bonded in a distorted see-saw-like geometry to one Li1+, two Nb5+, and one Cu1+ atom. In the third O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+ and two Nb5+ atoms. In the fourth O2- site, O2- is bonded in a distorted see-saw-like geometry to one Li1+, two Nb5+, and one Cu1+ atom. In the fifth O2- site, O2- is bonded in a distorted see-saw-like geometry to one Li1+, two Nb5+, and one Cu1+ atom. In the sixth O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+ and two Nb5+ atoms. In the seventh O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Nb5+, and one Cu1+ atom. In the eighth O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+ and two Nb5+ atoms. In the ninth O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Nb5+, and one Cu1+ atom. In the tenth O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+ and two Nb5+ atoms. In the eleventh O2- site, O2- is bonded in a 4-coordinate geometry to one Li1+, two Nb5+, and one Cu1+ atom. In the twelfth O2- site, O2- is bonded in a distorted see-saw-like geometry to two Li1+ and two Nb5+ atoms.
