Cu9C24H12(N6O13)2 crystallizes in the cubic Fm-3m space group. There are two inequivalent Cu sites. In the first Cu site, Cu(1) is bonded in a 5-coordinate geometry to two equivalent N(1), one O(2), one O(3), and one O(4) atom. Both Cu(1)-N(1) bond lengths are 1.95 Å. The Cu(1)-O(2) bond length is 2.17 Å. The Cu(1)-O(3) bond length is 2.02 Å. The Cu(1)-O(4) bond length is 1.97 Å. In the second Cu site, Cu(2) is bonded in a distorted rectangular see-saw-like geometry to four equivalent O(1) atoms. All Cu(2)-O(1) bond lengths are 1.98 Å. There are three inequivalent C sites. In the first C site, C(2) is bonded in a trigonal planar geometry to one C(3) and two equivalent C(1) atoms. The C(2)-C(3) bond length is 1.44 Å. Both C(2)-C(1) bond lengths are 1.36 Å. In the second C site, C(3) is bonded in a bent 120 degrees geometry to one C(2) and two equivalent O(1) atoms. Both C(3)-O(1) bond lengths are 1.25 Å. In the third C site, C(1) is bonded in a distorted bent 120 degrees geometry to one C(2), one N(1), and one H(1) atom. The C(1)-N(1) bond length is 1.33 Å. The C(1)-H(1) bond length is 0.93 Å. N(1) is bonded in a 3-coordinate geometry to one Cu(1), one C(1), and one N(1) atom. The N(1)-N(1) bond length is 1.34 Å. H(1) is bonded in a single-bond geometry to one C(1) atom. There are four inequivalent O sites. In the first O site, O(2) is bonded in a 2-coordinate geometry to one Cu(1) and one O(3) atom. The O(2)-O(3) bond length is 1.16 Å. In the second O site, O(3) is bonded in a single-bond geometry to one Cu(1) and one O(2) atom. In the third O site, O(1) is bonded in a distorted single-bond geometry to one Cu(2) and one C(3) atom. In the fourth O site, O(4) is bonded in a trigonal non-coplanar geometry to three equivalent Cu(1) atoms. Linkers: 39 [O]C(=O)C1=CN=N[CH]1 ,19 [O]C(=O)[C]1C=NN=C1 ,38 [O]C(=O)C1=C[N]N=C1.
