The crystal structure described by Co3O2BO3 crystallizes in the orthorhombic Pbam space group. There are four inequivalent Co sites. In the first Co site, Co(1) is bonded to one O(2), one O(3), two equivalent O(4), and two equivalent O(5) atoms to form a mixture of corner and edge-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles range from 16-60°. In the second Co site, Co(2) is bonded to one O(4), one O(5), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of corner and edge-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles range from 60-67°. In the third Co site, Co(3) is bonded to two equivalent O(5) and four equivalent O(2) atoms to form a mixture of corner and edge-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 67°. In the fourth Co site, Co(4) is bonded to two equivalent O(1) and four equivalent O(4) atoms to form a mixture of corner and edge-sharing CoO6 octahedra. The corner-sharing octahedral tilt angles are 16°. B(1) is bonded in a trigonal planar geometry to one O(1), one O(2), and one O(3) atom. There are five inequivalent O sites. In the first O site, O(5) is bonded to one Co(2), one Co(3), and two equivalent Co(1) atoms to form OCo4 tetrahedra that share corners with three equivalent O(4)Co5 square pyramids, corners with three equivalent O(5)Co4 tetrahedra, and  an edgeedge with one O(4)Co5 square pyramid. In the second O site, O(1) is bonded in a 4-coordinate geometry to one Co(4), two equivalent Co(2), and one B(1) atom. In the third O site, O(2) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), two equivalent Co(3), and one B(1) atom. In the fourth O site, O(3) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), two equivalent Co(2), and one B(1) atom. In the fifth O site, O(4) is bonded to one Co(2), two equivalent Co(1), and two equivalent Co(4) atoms to form OCo5 square pyramids that share corners with two equivalent O(4)Co5 square pyramids, corners with three equivalent O(5)Co4 tetrahedra, edges with three equivalent O(4)Co5 square pyramids, and  an edgeedge with one O(5)Co4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
