The crystal structure described by Co3(SeO3)4 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms to form edge-sharing CoO6 octahedra. In the second Co site, Co(2) is bonded to one O(1), one O(2), one O(4), one O(5), and two equivalent O(6) atoms to form edge-sharing CoO6 octahedra. There are two inequivalent Se sites. In the first Se site, Se(1) is bonded in a trigonal non-coplanar geometry to one O(1), one O(2), and one O(4) atom. In the second Se site, Se(2) is bonded in a trigonal non-coplanar geometry to one O(3), one O(5), and one O(6) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a trigonal non-coplanar geometry to one Co(1), one Co(2), and one Se(1) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to one Co(1), one Co(2), and one Se(1) atom. In the third O site, O(3) is bonded in a distorted bent 120 degrees geometry to one Co(1) and one Se(2) atom. In the fourth O site, O(4) is bonded in a bent 150 degrees geometry to one Co(2) and one Se(1) atom. In the fifth O site, O(5) is bonded in a bent 120 degrees geometry to one Co(2) and one Se(2) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to two equivalent Co(2) and one Se(2) atom. is represented by the Crystallographic Information File (CIF) [CIF]
