CuCd(CO2)4(CH2)2 crystallizes in the orthorhombic Pbcn space group. The structure consists of eight 02329_fluka molecules inside a CuCd(CO2)4 framework. In the CuCd(CO2)4 framework, Cu(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(2) atoms. Both Cu(1)-O(1) bond lengths are 1.91 Å. Both Cu(1)-O(2) bond lengths are 1.94 Å. Cd(1) is bonded in a 4-coordinate geometry to two equivalent O(3) and two equivalent O(4) atoms. Both Cd(1)-O(3) bond lengths are 2.35 Å. Both Cd(1)-O(4) bond lengths are 2.32 Å. There are two inequivalent C sites. In the first C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(4) atom. The C(2)-O(2) bond length is 1.27 Å. The C(2)-O(4) bond length is 1.24 Å. In the second C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(3) atom. The C(3)-O(1) bond length is 1.27 Å. The C(3)-O(3) bond length is 1.24 Å. There are four inequivalent O sites. In the first O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one C(3) atom. In the second O site, O(2) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one C(2) atom. In the third O site, O(3) is bonded in a distorted single-bond geometry to one Cd(1) and one C(3) atom. In the fourth O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one C(2) atom. Linkers: 8 [O]C(=O)CC([O])=O. Metal clusters: 4 [Cd] ,4 [Cu].
