Cd2H3O3Cl crystallizes in the orthorhombic Pnma space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to one O(1), four equivalent O(2), and one Cl(1) atom to form distorted CdClO5 octahedra that share edges with two equivalent Cd(1)ClO5 octahedra and edges with four equivalent Cd(2)Cl2O4 octahedra. In the second Cd site, Cd(2) is bonded to two equivalent O(1), two equivalent O(2), and two equivalent Cl(1) atoms to form distorted CdCl2O4 octahedra that share edges with two equivalent Cd(2)Cl2O4 octahedra and edges with four equivalent Cd(1)ClO5 octahedra. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(1) atom. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted single-bond geometry to one Cd(1), two equivalent Cd(2), and one H(2) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cd(2), two equivalent Cd(1), and one H(1) atom. Cl(1) is bonded in a 3-coordinate geometry to one Cd(1) and two equivalent Cd(2) atoms.
