CdC4H4O6 is Indium-like structured and crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of nine CdC4H4O6 clusters. Cd(1) is bonded in an octahedral geometry to two equivalent O(1), two equivalent O(2), and two equivalent O(3) atoms. There are two inequivalent C sites. In the first C site, C(1) is bonded in a single-bond geometry to one O(1) atom. In the second C site, C(2) is bonded in a single-bond geometry to one O(2) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(3) atom. In the second H site, H(2) is bonded in a single-bond geometry to one O(3) atom. There are three inequivalent O sites. In the first O site, O(1) is bonded in a 2-coordinate geometry to one Cd(1) and one C(1) atom. In the second O site, O(2) is bonded in a 2-coordinate geometry to one Cd(1) and one C(2) atom. In the third O site, O(3) is bonded in a distorted water-like geometry to one Cd(1), one H(1), and one H(2) atom.
