The crystal structure described by Cd(OH)2 crystallizes in the triclinic P1 space group. There are two inequivalent Cd sites. In the first Cd site, Cd(1) is bonded to one O(2), one O(4), two equivalent O(1), and two equivalent O(3) atoms to form a mixture of face, corner, and edge-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles range from 31-64°. In the second Cd site, Cd(2) is bonded to one O(2), one O(3), two equivalent O(1), and two equivalent O(4) atoms to form a mixture of face, corner, and edge-sharing CdO6 octahedra. The corner-sharing octahedral tilt angles range from 31-64°. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(2) atom. In the third H site, H(3) is bonded in a single-bond geometry to one O(3) atom. In the fourth H site, H(4) is bonded in a single-bond geometry to one O(4) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a single-bond geometry to two equivalent Cd(1), two equivalent Cd(2), and one H(1) atom. In the second O site, O(2) is bonded in a single-bond geometry to one Cd(1), one Cd(2), and one H(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Cd(2), two equivalent Cd(1), and one H(3) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to one Cd(1), two equivalent Cd(2), and one H(4) atom. is represented by the Crystallographic Information File (CIF) [CIF]
