CuC4H6(N2O3)2(CH2O)2 is Indium-derived structured and crystallizes in the tetragonal P4_32_12 space group. The structure is zero-dimensional and consists of eight methanol molecules and four CuC4H6(N2O3)2 clusters. In each CuC4H6(N2O3)2 cluster, Cu(1) is bonded in a rectangular see-saw-like geometry to two equivalent N(1) and two equivalent O(2) atoms. Both Cu(1)-N(1) bond lengths are 1.96 Å. Both Cu(1)-O(2) bond lengths are 1.97 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 N(1) and one N(2) atom. The C(1)-N(1) bond length is 1.32 Å. The C(1)-N(2) bond length is 1.33 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one O(2) and one O(3) atom. The C(2)-O(2) bond length is 1.29 Å. The C(2)-O(3) bond length is 1.25 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a distorted trigonal planar geometry to one Cu(1), one C(1), and one O(1) atom. The N(1)-O(1) bond length is 1.40 Å. In the second N site, N(2) is bonded in a trigonal planar geometry to one C(1), one H(2), and one H(3) atom. The N(2)-H(2) bond length is 1.04 Å. The N(2)-H(3) bond length is 1.02 Å. There are three inequivalent H sites. In the first H site, H(2) is bonded in a single-bond geometry to one N(2) atom. In the second H site, H(3) is bonded in a single-bond geometry to one N(2) atom. In the third H site, H(4) is bonded in a single-bond geometry to one O(1) atom. The H(4)-O(1) bond length is 0.99 Å. There are three inequivalent O sites. In the first O site, O(3) is bonded in a distorted single-bond geometry to one C(2) atom. In the second O site, O(2) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(2) atom. In the third O site, O(1) is bonded in a water-like geometry to one N(1) and one H(4) atom. Linkers: 1 [O]C(=O)[C@H](O)[C@@H](O)C([O])=O. Metal clusters: 4 [Cu].
