CdC3NH5SO2 crystallizes in the orthorhombic P2_12_12_1 space group. Cd(1) is bonded in a 6-coordinate geometry to one N(1), three equivalent S(1), one O(1), and one O(2) atom. The Cd(1)-N(1) bond length is 2.34 Å. There are a spread of Cd(1)-S(1) bond distances ranging from 2.61-2.93 Å. The Cd(1)-O(1) bond length is 2.28 Å. The Cd(1)-O(2) bond length is 2.55 Å. There are three inequivalent C sites. In the first C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(3)-O(1) bond length is 1.28 Å. The C(3)-O(2) bond length is 1.26 Å. In the second C site, C(1) is bonded in a distorted water-like geometry to one H(1), one H(2), and one S(1) atom. The C(1)-H(1) bond length is 1.10 Å. The C(1)-H(2) bond length is 1.10 Å. The C(1)-S(1) bond length is 1.83 Å. In the third C site, C(2) is bonded in a 2-coordinate geometry to one N(1) and one H(3) atom.
