CuH8(C2N)4 is Indium-like structured and crystallizes in the monoclinic C2/m space group. The structure is zero-dimensional and consists of two CuH8(C2N)4 clusters. Cu(1) is bonded in a square co-planar geometry to four equivalent N(1) atoms. All Cu(1)-N(1) bond lengths are 2.04 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 1.34 Å. The C(1)-H(1) bond length is 0.93 Å. In the second C site, C(2) is bonded in a distorted bent 120 degrees geometry to one N(1) and one H(2) atom. The C(2)-N(1) bond length is 1.34 Å. The C(2)-H(2) 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(2) 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(2) is bonded in a single-bond geometry to one C(2) atom. Linkers: 4 c1cnccn1.
