Materials Data on Li4CrO4 by Materials Project
Li4CrO4 crystallizes in the orthorhombic Cmcm space group. The structure is three-dimensional. there are two inequivalent Li1+ sites. In the first Li1+ site, Li1+ is bonded to four O2- atoms to form LiO4 tetrahedra that share corners with four equivalent CrO4 tetrahedra, corners with six LiO4 tetrahedra, and edges with three LiO4 tetrahedra. There is two shorter (1.93 Å) and two longer (1.98 Å) Li–O bond length. In the second Li1+ site, Li1+ is bonded to four O2- atoms to form distorted LiO4 tetrahedra that share corners with four equivalent CrO4 tetrahedra, corners with six LiO4 tetrahedra, and edges with three LiO4 tetrahedra. There are a spread of Li–O bond distances ranging from 2.00–2.14 Å. Cr4+ is bonded to four O2- atoms to form CrO4 tetrahedra that share corners with sixteen LiO4 tetrahedra. There is two shorter (1.81 Å) and two longer (1.82 Å) Cr–O bond length. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded to four Li1+ and one Cr4+ atom to form distorted corner-sharing OLi4Cr trigonal bipyramids. In the second O2- site, O2- is bonded in a 5-coordinate geometry to four Li1+ and one Cr4+ atom.
