CuC8(N2O)2 crystallizes in the cubic Pn-3m space group. Cu(1) is bonded in a rectangular see-saw-like geometry to four equivalent N(1) atoms. All Cu(1)-N(1) bond lengths are 1.98 Å. There are three inequivalent C sites. In the first C site, C(1) is bonded in a distorted single-bond geometry to one C(3) and one N(1) atom. The C(1)-C(3) bond length is 1.38 Å. The C(1)-N(1) bond length is 1.34 Å. In the second C site, C(2) is bonded in a trigonal planar geometry to two equivalent N(1) and one O(1) atom. Both C(2)-N(1) bond lengths are 1.37 Å. The C(2)-O(1) bond length is 1.23 Å. In the third C site, C(3) is bonded in a bent 120 degrees geometry to two equivalent C(1) atoms. N(1) is bonded in a trigonal planar geometry to one Cu(1), one C(1), and one C(2) atom. O(1) is bonded in a single-bond geometry to one C(2) atom. Linkers: 24 O=C1N=[C][C][C]=N1. Metal clusters: 12 [Cu]. The MOF has largest included sphere 6.68 A, density 1.29 g/cm3, surface area 4135.69 m2/g, accessible volume 0.40 cm3/g
