The compound described by Be(CoO2)2 is Spinel structured and crystallizes in the cubic Fd-3m space group. Be(1) is bonded to four equivalent O(1) atoms to form BeO4 tetrahedra that share corners with twelve equivalent Co(1)O6 octahedra. The corner-sharing octahedral tilt angles are 56°. Co(1) is bonded to six equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Be(1)O4 tetrahedra and edges with six equivalent Co(1)O6 octahedra. O(1) is bonded in a distorted rectangular see-saw-like geometry to one Be(1) and three equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
