Materials Data on CuNCl3 by Materials Project
(CuCl3)2N2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonia molecules and two CuCl3 clusters. In each CuCl3 cluster, Cu2+ is bonded in a rectangular see-saw-like geometry to four Cl1- atoms. There are a spread of Cu–Cl bond distances ranging from 2.14–2.24 Å. There are three 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. In the third Cl1- site, Cl1- is bonded in an L-shaped geometry to two equivalent Cu2+ atoms.
