K2MoSO3 crystallizes in the monoclinic C2/m space group. There are two inequivalent K sites. In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent O(1), and four equivalent O(2) atoms. In the second K site, K(2) is bonded in a 9-coordinate geometry to three equivalent S(1), two equivalent O(1), and four equivalent O(2) atoms. Mo(1) is bonded in a distorted tetrahedral geometry to one S(1), one O(1), and two equivalent O(2) atoms. S(1) is bonded in a 6-coordinate geometry to two equivalent K(1), three equivalent K(2), and one Mo(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a 1-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Mo(1) atom. In the second O site, O(2) is bonded in a 5-coordinate geometry to two equivalent K(1), two equivalent K(2), and one Mo(1) atom.

In the first K site, K(1) is bonded in a 8-coordinate geometry to two equivalent S(1), two equivalent O(1), and four equivalent O(2) atoms. There is one shorter (3.17 Å) and one longer (3.18 Å) K(1)-S(1) bond length. Both K(1)-O(1) bond lengths are 3.27 Å. There are two shorter (2.79 Å) and two longer (2.92 Å) K(1)-O(2) bond lengths. In the second K site, K(2) is bonded in a 9-coordinate geometry to three equivalent S(1), two equivalent O(1), and four equivalent O(2) atoms. There are two shorter (3.33 Å) and one longer (3.63 Å) K(2)-S(1) bond length. There is one shorter (2.84 Å) and one longer (3.07 Å) K(2)-O(1) bond length.
