The crystal structure described by Cd(HCOO)2 crystallizes in the monoclinic C2/c space group. Cd(1) is bonded to one O(2), two equivalent O(1), two equivalent O(3), and two equivalent O(4) atoms to form distorted edge-sharing CdO7 pentagonal bipyramids. There are two inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one H(1), one O(1), and one O(2) atom. In the second C site, C(2) is bonded in a trigonal planar geometry to one H(2), one O(3), and one O(4) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted trigonal planar geometry to two equivalent Cd(1) and one C(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cd(1) and one C(1) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to two equivalent Cd(1) and one C(2) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Cd(1) and one C(2) atom. is represented by the CIF card [CIF]
