The crystal structure described by K2Co2(SeO3)3 crystallizes in the hexagonal P6_3mc space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 10-coordinate geometry to one Se(3), three equivalent O(2), and six equivalent O(1) atoms. In the second K site, K(2) is bonded in a 9-coordinate geometry to three equivalent O(1) and six equivalent O(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to three equivalent O(1) and three equivalent O(3) atoms to form face-sharing CoO6 octahedra. In the second Co site, Co(2) is bonded to three equivalent O(2) and three equivalent O(3) atoms to form face-sharing CoO6 octahedra. There are three inequivalent Se sites. In the first Se site, Se(1) is bonded in a trigonal non-coplanar geometry to three equivalent O(1) atoms. In the second Se site, Se(2) is bonded in a distorted trigonal non-coplanar geometry to three equivalent O(2) atoms. In the third Se site, Se(3) is bonded in a trigonal non-coplanar geometry to one K(1) and three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 5-coordinate geometry to one K(2), two equivalent K(1), one Co(1), and one Se(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to one K(1), two equivalent K(2), one Co(2), and one Se(2) atom. In the third O site, O(3) is bonded in a distorted T-shaped geometry to one Co(1), one Co(2), and one Se(3) atom. is represented by the CIF card [CIF]
