Materials Data on LiTiCoO4 by Materials Project

LiCoTiO4 is Spinel-derived structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with six equivalent TiO6 octahedra and corners with six equivalent CoO6 octahedra. The corner-sharing octahedra tilt angles range from 57–62°. There are two shorter (2.01 Å) and two longer (2.02 Å) Li–O bond lengths. Ti4+ is bonded to six O2- atoms to form TiO6 octahedra that share corners with six equivalent LiO4 tetrahedra, edges with two equivalent TiO6 octahedra, and edges with four equivalent CoO6 octahedra. All Ti–O bond lengths are 1.98 Å. Co3+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six equivalent LiO4 tetrahedra, edges with two equivalent CoO6 octahedra, and edges with four equivalent TiO6 octahedra. There are four shorter (2.00 Å) and two longer (2.09 Å) Co–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Li1+, two equivalent Ti4+, and one Co3+ atom. In the second O2- site, O2- is bonded to one Li1+, one Ti4+, and two equivalent Co3+ atoms to form a mixture of distorted corner and edge-sharing OLiTiCo2 tetrahedra.
