Materials Data on CuH8CN5Cl3 by Materials Project
(CuCN4HCl)2(NH2)2(H2)3(HCl)4 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four ammonia molecules, eight hydrochloric acid molecules, six hydrogen molecules, and four CuCN4HCl clusters. In each CuCN4HCl cluster, Cu2+ is bonded in a bent 150 degrees geometry to one N+2.20- and one Cl1- atom. The Cu–N bond length is 1.82 Å. The Cu–Cl bond length is 2.08 Å. C4+ is bonded in a 1-coordinate geometry to three N+2.20- atoms. There are a spread of C–N bond distances ranging from 1.27–1.43 Å. There are four inequivalent N+2.20- sites. In the first N+2.20- site, N+2.20- is bonded in a distorted bent 120 degrees geometry to one C4+ and one N+2.20- atom. The N–N bond length is 1.40 Å. In the second N+2.20- site, N+2.20- is bonded in a 2-coordinate geometry to one Cu2+, one C4+, and one N+2.20- atom. The N–N bond length is 1.37 Å. In the third N+2.20- site, N+2.20- is bonded in a single-bond geometry to one N+2.20- and one H1+ atom. The N–H bond length is 1.03 Å. In the fourth N+2.20- site, N+2.20- is bonded in a 1-coordinate geometry to one C4+ and one N+2.20- atom. H1+ is bonded in a single-bond geometry to one N+2.20- atom. Cl1- is bonded in a single-bond geometry to one Cu2+ atom.
