The structure described by Co5O8 is beta indium sulfide-like structured and crystallizes in the tetragonal I-4m2 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to three equivalent O(1) and three equivalent O(2) atoms to form CoO6 octahedra that share corners with three equivalent Co(2)O4 tetrahedra and edges with six equivalent Co(1)O6 octahedra. In the second Co site, Co(2) is bonded to four equivalent O(1) atoms to form corner-sharing CoO4 tetrahedra. The corner-sharing octahedral tilt angles are 59°. There are two inequivalent O sites. In the first O site, O(1) is bonded to one Co(2) and three equivalent Co(1) atoms to form a mixture of distorted corner and edge-sharing OCo4 trigonal pyramids. In the second O site, O(2) is bonded in a distorted T-shaped geometry to three equivalent Co(1) atoms. is represented by the CIF card [CIF]
