Materials Data on Cu(NCl2)2 by Materials Project
CuCl4N2 crystallizes in the orthorhombic Cmce space group. The structure is zero-dimensional and consists of eight ammonia molecules and four CuCl4 clusters. In each CuCl4 cluster, Cu2+ is bonded in a square co-planar geometry to four Cl1- atoms. All Cu–Cl bond lengths are 2.15 Å. There are two inequivalent Cl1- sites. In the first Cl1- site, Cl1- is bonded in a single-bond geometry to one Cu2+ atom. In the second Cl1- site, Cl1- is bonded in a single-bond geometry to one Cu2+ atom.
