The material structure described by KSO3 crystallizes in the trigonal P321 space group. There are two inequivalent K sites. In the first K site, K(1) is bonded to two equivalent O(1), two equivalent O(3), and four equivalent O(2) atoms to form corner-sharing KO8 hexagonal bipyramids. In the second K site, K(2) is bonded in a 6-coordinate geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are three inequivalent S sites. In the first S site, S(1) is bonded in a trigonal non-coplanar geometry to three equivalent O(1) atoms. In the second S site, S(2) is bonded in a trigonal non-coplanar geometry to three equivalent O(2) atoms. In the third S site, S(3) is bonded in a trigonal non-coplanar geometry to three equivalent O(3) atoms. There are three inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one S(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one K(2), two equivalent K(1), and one S(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one K(1), one K(2), and one S(3) atom. is represented by the CIF file [CIF]
