The crystal structure described by K2SO3 crystallizes in the trigonal P-3m1 space group. There are three inequivalent K sites. In the first K site, K(1) is bonded in a 10-coordinate geometry to one S(1) and nine equivalent O(1) atoms. In the second K site, K(2) is bonded to six equivalent O(1) atoms to form face-sharing KO6 octahedra. In the third K site, K(3) is bonded to six equivalent O(1) atoms to form face-sharing KO6 octahedra. S(1) is bonded in a trigonal non-coplanar geometry to one K(1) and three equivalent O(1) atoms. O(1) is bonded in a 6-coordinate geometry to one K(2), one K(3), three equivalent K(1), and one S(1) atom. is represented by the CIF file [CIF]
