CuC2H2O5(CH2)2 is Indium-derived structured and crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four 02329_fluka molecules and one CuC2H2O5 cluster. In the CuC2H2O5 cluster, Cu(1) is bonded in a square pyramidal geometry to one O(1), one O(2), one O(3), one O(4), and one O(5) atom. The Cu(1)-O(1) bond length is 1.99 Å. The Cu(1)-O(2) bond length is 2.01 Å. The Cu(1)-O(3) bond length is 1.98 Å. The Cu(1)-O(4) bond length is 2.01 Å. The Cu(1)-O(5) bond length is 2.18 Å. There are two inequivalent C sites. In the first 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 1.27 Å. The C(1)-O(2) bond length is 1.28 Å. In the second C site, C(4) is bonded in a distorted bent 120 degrees geometry to one O(3) and one O(4) atom. The C(4)-O(3) bond length is 1.27 Å. The C(4)-O(4) bond length is 1.28 Å. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one O(5) atom. The H(1)-O(5) bond length is 0.98 Å. In the second H site, H(2) is bonded in a single-bond geometry to one O(5) atom. The H(2)-O(5) bond length is 0.98 Å. There are five inequivalent O sites. In the first O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(1) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(1) atom. In the third O site, O(3) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(4) atom. In the fourth O site, O(4) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(4) atom. In the fifth O site, O(5) is bonded in a distorted water-like geometry to one Cu(1), one H(1), and one H(2) atom. Linkers: 2 [O]C(=O)CCC([O])=O.
