(CuC2N3H)2(CH)3 crystallizes in the monoclinic C2/c space group. The structure consists of twelve 02329_fluka molecules inside a CuC2N3H framework. In the CuC2N3H framework, Cu(1) is bonded in a trigonal planar geometry to one N(1), one N(2), and one N(3) atom. The Cu(1)-N(1) bond length is 1.81 Å. The Cu(1)-N(2) bond length is 1.95 Å. The Cu(1)-N(3) bond length is 1.93 Å. There are three inequivalent C sites. In the first C site, C(3) is bonded in a distorted single-bond geometry to one C(4) and one H(3) atom. The C(3)-C(4) bond length is 1.41 Å. The C(3)-H(3) bond length is 1.09 Å. In the second C site, C(4) is bonded in a trigonal planar geometry to one C(5) and two equivalent C(3) atoms. The C(4)-C(5) bond length is 1.45 Å. In the third C site, C(5) is bonded in a distorted trigonal planar geometry to one C(4) and two equivalent N(3) atoms. Both C(5)-N(3) bond lengths are 1.35 Å. There are three inequivalent N sites. In the first N site, N(3) is bonded in a 3-coordinate geometry to one Cu(1), one C(5), and one N(2) atom. The N(3)-N(2) bond length is 1.36 Å. In the second N site, N(1) is bonded in a distorted bent 150 degrees geometry to one Cu(1) and one N(1) atom. The N(1)-N(1) bond length is 1.17 Å. In the third N site, N(2) is bonded in a distorted trigonal planar geometry to one Cu(1), one N(2), and one N(3) atom. The N(2)-N(2) bond length is 1.34 Å. H(3) is bonded in a single-bond geometry to one C(3) atom. Linkers: 2 c1ccc(C2=NN=N[N]2)cc1. Metal clusters: 4 [Cu].
