Cu2C21H20(NO)4(CH)4 crystallizes in the tetragonal I4_1/a space group. The structure consists of sixteen 02329_fluka molecules inside a Cu2C21H20(NO)4 framework. In the Cu2C21H20(NO)4 framework, Cu(1) is bonded in a linear geometry to two equivalent N(1) atoms. Both Cu(1)-N(1) bond lengths are 2.02 Å. There are six 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 H(1) atom. The C(1)-N(1) bond length is 1.32 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(3) is bonded in a distorted single-bond geometry to one C(4) and one O(1) atom. The C(3)-C(4) bond length is 1.38 Å. The C(3)-O(1) bond length is 1.35 Å. In the third C site, C(4) is bonded in a distorted trigonal planar geometry to one C(3), one C(5), and one H(3) atom. The C(4)-C(5) bond length is 1.37 Å. The C(4)-H(3) bond length is 0.93 Å. In the fourth C site, C(5) is bonded in a distorted bent 120 degrees geometry to one C(4), one N(1), and one H(4) atom. The C(5)-N(1) bond length is 1.31 Å. The C(5)-H(4) bond length is 0.93 Å. In the fifth C site, C(6) is bonded in a distorted trigonal non-coplanar geometry to one C(7); two equivalent H(5,6); and one O(1) atom. The C(6)-C(7) bond length is 1.53 Å. Both C(6)-H(5,6) bond lengths are 0.97 Å. The C(6)-O(1) bond length is 1.43 Å. In the sixth C site, C(7) is bonded in a tetrahedral geometry to four equivalent C(6) atoms. N(1) is bonded in a trigonal planar geometry to one Cu(1), one C(1), and one C(5) atom. There are four inequivalent H sites. In the first H site, H(1) is bonded in a single-bond geometry to one C(1) atom. In the second H site, H(3) is bonded in a single-bond geometry to one C(4) atom. In the third H site, H(4) is bonded in a single-bond geometry to one C(5) atom. In the fourth H site, H(5,6) is bonded in a single-bond geometry to one C(6) atom. O(1) is bonded in a bent 120 degrees geometry to one C(3) and one C(6) atom. Linkers: 2 c1cc(OCC(COc2ccncc2)(COc2ccncc2)COc2ccncc2)ccn1. Metal clusters: 4 [Cu].
