The crystal structure described by Co3BiO8 is trigonal omega-derived structured and crystallizes in the trigonal R-3m space group. Co(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form CoO6 octahedra that share edges with two equivalent Bi(1)O6 octahedra and edges with four equivalent Co(1)O6 octahedra. Bi(1) is bonded to six equivalent O(1) atoms to form distorted BiO6 octahedra that share edges with six equivalent Co(1)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 3-coordinate geometry to two equivalent Co(1) and one Bi(1) atom. In the second O site, O(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent Co(1) atoms. is represented by the CIF file [CIF]
