Materials Data on Be(CoO2)2 by Materials Project

Be(CoO2)2 is Spinel structured and crystallizes in the cubic Fd-3m space group. The structure is three-dimensional. Be2+ is bonded to four equivalent O2- atoms to form BeO4 tetrahedra that share corners with twelve equivalent CoO6 octahedra. The corner-sharing octahedral tilt angles are 56°. All Be–O bond lengths are 1.71 Å. Co3+ is bonded to six equivalent O2- atoms to form CoO6 octahedra that share corners with six equivalent BeO4 tetrahedra and edges with six equivalent CoO6 octahedra. All Co–O bond lengths are 1.92 Å. O2- is bonded in a distorted rectangular see-saw-like geometry to one Be2+ and three equivalent Co3+ atoms.
