CuC5H5(NO2)2CH crystallizes in the triclinic P-1 space group. The structure consists of two 02329_fluka molecules inside a CuC5H5(NO2)2 framework. In the CuC5H5(NO2)2 framework, Cu(1,2) is bonded in an octahedral geometry to two equivalent N(1,2); two equivalent O(1,2); and two equivalent O(3,4) atoms. Both Cu(1,2)-N(1,2) bond lengths are 2.02 Å. Both Cu(1,2)-O(1,2) bond lengths are 2.48 Å. Both Cu(1,2)-O(3,4) bond lengths are 2.00 Å. There are three inequivalent C sites. In the first C site, C(1,2) is bonded in a trigonal planar geometry to one H(1,2); one O(1,2); and one O(3,4) atom. The C(1,2)-H(1,2) bond length is 1.11 Å. The C(1,2)-O(1,2) bond length is 1.26 Å. The C(1,2)-O(3,4) bond length is 1.29 Å. In the second C site, C(3,4) is bonded in a distorted bent 120 degrees geometry to one N(1,2) and one H(3,4) atom. The C(3,4)-N(1,2) bond length is 1.35 Å. The C(3,4)-H(3,4) bond length is 1.09 Å. In the third C site, C(6) is bonded in a trigonal planar geometry to two equivalent N(1,2) and one H(6) atom. Both C(6)-N(1,2) bond lengths are 1.34 Å. The C(6)-H(6) bond length is 1.09 Å. N(1,2) is bonded in a trigonal planar geometry to one Cu(1,2); one C(3,4); and one C(6) atom. There are three inequivalent H sites. In the first H site, H(1,2) is bonded in a single-bond geometry to one C(1,2) atom. In the second H site, H(3,4) is bonded in a single-bond geometry to one C(3,4) atom. In the third H site, H(6) is bonded in a single-bond geometry to one C(6) atom. There are two inequivalent O sites. In the first O site, O(3,4) is bonded in a bent 120 degrees geometry to one Cu(1,2) and one C(1,2) atom. In the second O site, O(1,2) is bonded in a distorted single-bond geometry to one Cu(1,2) and one C(1,2) atom. Linkers: 2 c1cncnc1. Metal clusters: 2 [Cu].
