Materials Data on H9CN5Cl2 by Materials Project
(CN5H9Cl)2Cl2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of four hydrochloric acid molecules and four CN5H9Cl clusters. In each CN5H9Cl cluster, C4+ is bonded in a trigonal planar geometry to three N+2.20- atoms. There are a spread of C–N bond distances ranging from 1.32–1.37 Å. There are five inequivalent N+2.20- sites. In the first N+2.20- site, N+2.20- is bonded in a trigonal planar geometry to one C4+ and two H1+ atoms. There is one shorter (1.02 Å) and one longer (1.03 Å) N–H bond length. In the second N+2.20- site, N+2.20- is bonded in a trigonal non-coplanar geometry to one N+2.20- and three H1+ atoms. The N–N bond length is 1.43 Å. There is one shorter (1.05 Å) and two longer (1.06 Å) N–H bond length. In the third N+2.20- site, N+2.20- is bonded in a water-like geometry to one N+2.20- and two H1+ atoms. The N–N bond length is 1.40 Å. Both N–H bond lengths are 1.03 Å. In the fourth N+2.20- site, N+2.20- is bonded in a 2-coordinate geometry to one C4+, one N+2.20-, and one H1+ atom. The N–H bond length is 1.05 Å. In the fifth N+2.20- site, N+2.20- is bonded in a 3-coordinate geometry to one C4+, one N+2.20-, and one H1+ atom. The N–H bond length is 1.03 Å. There are nine inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- and one Cl1- atom. The H–Cl bond length is 2.07 Å. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one N+2.20- atom. Cl1- is bonded in a distorted single-bond geometry to one H1+ atom.
