Cu(C6H4NO2)2 is Indium-derived structured and crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of eight 02329_fluka molecules and four CuC10H6(NO2)2 clusters. In each CuC10H6(NO2)2 cluster, Cu(1) is bonded in a square co-planar geometry to one N(1), one N(2), and two equivalent O(1) atoms. The Cu(1)-N(1) bond length is 1.94 Å. The Cu(1)-N(2) bond length is 1.90 Å. Both Cu(1)-O(1) bond lengths are 2.05 Å. There are five inequivalent C sites. In the first C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one O(1), and one O(2) atom. The C(1)-C(2) bond length is 1.51 Å. The C(1)-O(1) bond length is 1.30 Å. The C(1)-O(2) bond length is 1.24 Å. In the second C site, C(2) is bonded in a distorted trigonal planar geometry to one C(1), one C(3), and one N(2) atom. The C(2)-C(3) bond length is 1.39 Å. The C(2)-N(2) bond length is 1.34 Å. In the third C site, C(3) is bonded in a distorted single-bond geometry to one C(2) and one H(1) atom. The C(3)-H(1) bond length is 1.09 Å. In the fourth C site, C(5) is bonded in a distorted trigonal planar geometry to one C(6), one N(1), and one H(3) atom. The C(5)-C(6) bond length is 1.39 Å. The C(5)-N(1) bond length is 1.35 Å. The C(5)-H(3) bond length is 1.09 Å. In the fifth C site, C(6) is bonded in a distorted single-bond geometry to one C(5) and one H(4) atom. The C(6)-H(4) bond length is 1.09 Å. There are two inequivalent N sites. In the first N site, N(1) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent C(5) atoms. In the second N site, N(2) is bonded in a trigonal planar geometry to one Cu(1) and two equivalent C(2) atoms. There are three inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(3) atom. In the second H site, H(3) is bonded in a single-bond geometry to one C(5) atom. In the third H site, H(4) is bonded in a single-bond geometry to one C(6) atom. There are two inequivalent O sites. In the first O site, O(2) is bonded in a single-bond geometry to one C(1) atom. In the second O site, O(1) is bonded in a bent 120 degrees geometry to one Cu(1) and one C(1) atom. Linkers: 2 [O]C(=O)c1cccc(C([O])=O)n1. Metal clusters: 2 [Cu].
