CuCdH4(C2O5)2(CH2)2(H2O)2 crystallizes in the orthorhombic Pbcn space group. The structure consists of eight 02329_fluka molecules and eight water molecules inside a CuCdH4(C2O5)2 framework. In the CuCdH4(C2O5)2 framework, Cu(1) is bonded in a square co-planar geometry to two equivalent O(1) and two equivalent O(5) atoms. Both Cu(1)-O(1) bond lengths are 1.91 Å. Both Cu(1)-O(5) bond lengths are 1.96 Å. Cd(1) is bonded in a distorted octahedral geometry to two equivalent O(2), two equivalent O(3), and two equivalent O(4) atoms. Both Cd(1)-O(2) bond lengths are 2.45 Å. Both Cd(1)-O(3) bond lengths are 2.29 Å. Both Cd(1)-O(4) bond lengths are 2.39 Å. There are two inequivalent C sites. In the first C site, C(3) is bonded in a distorted bent 120 degrees geometry to one O(4) and one O(5) atom. The C(3)-O(4) bond length is 1.26 Å. The C(3)-O(5) bond length is 1.29 Å. In the second C site, C(1) is bonded in a distorted bent 120 degrees geometry to one O(1) and one O(2) atom. The C(1)-O(1) bond length is 1.29 Å. The C(1)-O(2) bond length is 1.26 Å. There are two inequivalent H sites. In the first H site, H(4) is bonded in a single-bond geometry to one O(3) atom. The H(4)-O(3) bond length is 1.00 Å. In the second H site, H(3) is bonded in a single-bond geometry to one O(3) atom. The H(3)-O(3) bond length is 0.99 Å. There are five inequivalent O sites. In the first O site, O(3) is bonded in a distorted water-like geometry to one Cd(1), one H(3), and one H(4) atom. In the second O site, O(4) is bonded in a distorted bent 120 degrees geometry to one Cd(1) and one C(3) atom. In the third O site, O(1) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one C(1) atom. In the fourth O site, O(5) is bonded in a distorted bent 120 degrees geometry to one Cu(1) and one C(3) atom. In the fifth O site, O(2) is bonded in a distorted single-bond geometry to one Cd(1) and one C(1) atom. Linkers: 8 [O]C(=O)CC([O])=O. Metal clusters: 4 [Cd] ,4 [Cu].
