ZnC3(ZnC)2 is Cyanogen Chloride-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two ZnC clusters and two ZnC3 clusters. In each ZnC cluster, Zn(2,3) is bonded in a distorted linear geometry to one Zn(2,3) and one C(4,5) atom. The Zn(2,3)-Zn(2,3) bond length is 0.40 Å. The Zn(2,3)-C(4,5) bond length is 0.77 Å. C(4,5) is bonded in a single-bond geometry to one Zn(2,3) atom. In each ZnC3 cluster, Zn(1) is bonded in a linear geometry to one C(2) and one C(3) atom. The Zn(1)-C(2) bond length is 0.68 Å. The Zn(1)-C(3) bond length is 0.68 Å. There are three inequivalent C sites. In the first C site, C(3) is bonded in a distorted single-bond geometry to one Zn(1) and one C(1) atom. The C(3)-C(1) bond length is 0.70 Å. In the second C site, C(1) is bonded in a single-bond geometry to one C(3) atom. In the third C site, C(2) is bonded in a single-bond geometry to one Zn(1) atom.
