CdC3H2O5CH2 crystallizes in the orthorhombic P2_12_12_1 space group. The structure consists of four 02329_fluka molecules inside a CdC3H2O5 framework. In the CdC3H2O5 framework, Cd(1) is bonded in a 7-coordinate geometry to one O(1), one O(2), one O(3), two equivalent O(4), and two equivalent O(5) atoms. The Cd(1)-O(1) bond length is 2.23 Å. The Cd(1)-O(2) bond length is 2.43 Å. The Cd(1)-O(3) bond length is 2.34 Å. There is one shorter (2.39 Å) and one longer (2.65 Å) Cd(1)-O(4) bond length. Both Cd(1)-O(5) bond lengths are 2.36 Å. There are three inequivalent C sites. In the first C site, C(4) is bonded in a distorted bent 120 degrees geometry to one O(4) and one O(5) atom. The C(4)-O(4) bond length is 1.26 Å. The C(4)-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 1.28 Å. The C(1)-O(2) bond length is 1.27 Å. In the third C site, C(2) is bonded in a distorted water-like geometry to one H(2) and one O(3) atom. The C(2)-H(2) bond length is 1.10 Å. The C(2)-O(3) bond length is 1.43 Å. 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. The H(1)-O(3) bond length is 0.99 Å. In the second H site, H(2) is bonded in a single-bond geometry to one C(2) atom. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cd(1) and one C(1) atom. In the second O site, O(2) is bonded in a distorted single-bond geometry to one Cd(1) and one C(1) atom. In the third O site, O(3) is bonded in a 3-coordinate geometry to one Cd(1), one C(2), and one H(1) atom. In the fourth O site, O(4) is bonded in a distorted single-bond geometry to two equivalent Cd(1) and one C(4) atom. In the fifth O site, O(5) is bonded in a distorted single-bond geometry to two equivalent Cd(1) and one C(4) atom. Linkers: 4 [O]C(=O)C[C@H](O)C([O])=O. Metal clusters: 4 [Cd].
