Cu2C8N4H8Cl(C3H2)4 is Indium-derived structured and crystallizes in the orthorhombic Pnnn space group. The structure is zero-dimensional and consists of four 2,3-dimethyl-1,3-butadiene molecules and two Cu2C8N4H8Cl clusters. In each Cu2C8N4H8Cl cluster, Cu(1) is bonded in a 3-coordinate geometry to two equivalent N(1) and one Cl(1) atom. Both Cu(1)-N(1) bond lengths are 1.94 Å. The Cu(1)-Cl(1) bond length is 2.38 Å. There are two 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 1.33 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(5) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(4) atom. The C(5)-N(1) bond length is 1.32 Å. The C(5)-H(4) bond length is 0.93 Å. N(1) is bonded in a trigonal planar geometry to one Cu(1), one C(1), and one C(5) atom. There are two 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(4) is bonded in a single-bond geometry to one C(5) atom. Cl(1) is bonded in a linear geometry to two equivalent Cu(1) atoms. Linkers: 5 c1cc(-c2ccncc2)ccn1 ,4 [c]1cc(-c2ccncc2)ccn1. Metal clusters: 2 Cl[Cu].[Cu].
