CuH24(C2N)12(C3H2)4 is Marcasite structured and crystallizes in the tetragonal P-4n2 space group. The structure is zero-dimensional and consists of four 2,3-dimethyl-1,3-butadiene molecules and two CuH24(C2N)12 clusters. In each CuH24(C2N)12 cluster, Cu(1) is bonded in a rectangular see-saw-like geometry to four equivalent N(3) atoms. All Cu(1)-N(3) bond lengths are 2.03 Å. There are six inequivalent C sites. In the first C site, C(1) is bonded in a trigonal planar geometry to one C(2), one C(6), and one C(7) atom. The C(1)-C(2) bond length is 1.38 Å. The C(1)-C(6) bond length is 1.42 Å. The C(1)-C(7) bond length is 1.51 Å. In the second C site, C(2) is bonded in a distorted single-bond geometry to one C(1) and one H(1,4) atom. The C(2)-H(1,4) bond length is 0.93 Å. In the third C site, C(7) is bonded in a 3-coordinate geometry to one C(1), one N(1), one H(5), and one H(6) atom. The C(7)-N(1) bond length is 1.48 Å. The C(7)-H(5) bond length is 0.97 Å. The C(7)-H(6) bond length is 0.97 Å. In the fourth C site, C(8) is bonded in a trigonal planar geometry to one N(2), one N(3), and one H(7) atom. The C(8)-N(2) bond length is 1.30 Å. The C(8)-N(3) bond length is 1.35 Å. The C(8)-H(7) bond length is 0.93 Å. In the fifth C site, C(9) is bonded in a trigonal planar geometry to one N(1), one N(3), and one H(8) atom. The C(9)-N(1) bond length is 1.31 Å. The C(9)-N(3) bond length is 1.32 Å. The C(9)-H(8) bond length is 0.93 Å. In the sixth C site, C(6) is bonded in a distorted single-bond geometry to one C(1) and one H(1,4) atom. The C(6)-H(1,4) bond length is 0.93 Å. There are three inequivalent N sites. In the first N site, N(1) is bonded in a 2-coordinate geometry to one C(7), one C(9), and one N(2) atom. The N(1)-N(2) bond length is 1.34 Å. In the second N site, N(2) is bonded in a water-like geometry to one C(8) and one N(1) atom. In the third N site, N(3) is bonded in a trigonal planar geometry to one Cu(1), one C(8), and one C(9) atom. There are five inequivalent H sites. In the first H site, H(1,4) is bonded in a single-bond geometry to one C(2) atom. In the second H site, H(5) is bonded in a single-bond geometry to one C(7) atom. In the third H site, H(6) is bonded in a single-bond geometry to one C(7) atom. In the fourth H site, H(7) is bonded in a single-bond geometry to one C(8) atom. In the fifth H site, H(8) is bonded in a single-bond geometry to one C(9) atom. Linkers: 2 c1ncn(Cc2ccc(-c3ccc(Cn4cncn4)cc3)cc2)n1. Metal clusters: 2 [Cu].
