CuC4NH2O4(CH3)2 is Indium-derived structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of eight 02329_fluka molecules and two CuC4NH2O4 clusters. In each CuC4NH2O4 cluster, Cu(1) is bonded in a square pyramidal geometry to one N(1), two equivalent O(1), and two equivalent O(2) atoms. The Cu(1)-N(1) bond length is 2.18 Å. Both Cu(1)-O(1) bond lengths are 2.00 Å. Both Cu(1)-O(2) bond lengths are 2.01 Å. There are three 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 1.28 Å. The C(1)-O(2) bond length is 1.28 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(1) atom. The C(2)-N(1) bond length is 1.34 Å. The C(2)-H(1) bond length is 1.09 Å. In the third C site, C(3) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(2) atom. The C(3)-N(1) bond length is 1.34 Å. The C(3)-H(2) bond length is 1.09 Å. N(1) is bonded in a trigonal planar geometry to one Cu(1), one C(2), and one C(3) atom. There are two inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(2) is bonded in a single-bond geometry to one C(3) atom. There are two 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.
