The structure described by Co(BiO3)2 is Hydrophilite-derived structured and crystallizes in the trigonal P321 space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to six equivalent O(1) atoms to form CoO6 octahedra that share corners with six equivalent Bi(2)O6 octahedra and edges with three equivalent Bi(1)O6 octahedra. The corner-sharing octahedral tilt angles are 54°. In the second Co site, Co(2) is bonded to three equivalent O(2) and three equivalent O(3) atoms to form CoO6 octahedra that share corners with six equivalent Bi(1)O6 octahedra and edges with three equivalent Bi(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-53°. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with four equivalent Co(2)O6 octahedra, corners with six equivalent Bi(2)O6 octahedra, and  an edgeedge with one Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 49-58°. In the second Bi site, Bi(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form BiO6 octahedra that share corners with two equivalent Co(1)O6 octahedra, corners with six equivalent Bi(1)O6 octahedra, and edges with two equivalent Co(2)O6 octahedra. The corner-sharing octahedral tilt angles range from 54-58°. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Co(1), one Bi(1), and one Bi(2) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Co(2), one Bi(1), and one Bi(2) atom. In the third O site, O(3) is bonded in a distorted trigonal planar geometry to one Co(2), one Bi(1), and one Bi(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
