CdSO3 crystallizes in the monoclinic P2_1/c space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to one O(1), one O(3), one O(4), one O(6), and two equivalent O(5) atoms to form a mixture of distorted corner and edge-sharing CdO6 pentagonal pyramids. In the second Cd site, Cd(2) is bonded to one O(1), one O(3), one O(4), one O(6), and two equivalent O(2) atoms to form distorted corner-sharing CdO6 pentagonal pyramids. There are two inequivalent S sites. In the first S site, S(1) is bonded in a trigonal non-coplanar geometry to one O(2), one O(4), and one O(6) atom. In the second S site, S(2) is bonded in a trigonal non-coplanar geometry to one O(1), one O(3), and one O(5) atom. There are six inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to one Cd(1), one Cd(2), and one S(2) atom. In the second O site, O(2) is bonded in a distorted trigonal planar geometry to two equivalent Cd(2) and one S(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Cd(1), one Cd(2), and one S(2) atom. In the fourth O site, O(4) is bonded in a distorted trigonal planar geometry to one Cd(1), one Cd(2), and one S(1) atom. In the fifth O site, O(5) is bonded in a distorted trigonal planar geometry to two equivalent Cd(1) and one S(2) atom. In the sixth O site, O(6) is bonded in a trigonal planar geometry to one Cd(1), one Cd(2), and one S(1) atom.
