Materials Data on CrH9(CN2)3 by Materials Project
CrCr(NH3)6(CN)6 crystallizes in the trigonal R-3 space group. The structure is zero-dimensional and consists of three chromium molecules, eighteen hydrogen cyanide molecules, and three Cr(NH3)6 clusters. In each Cr(NH3)6 cluster, Cr3+ is bonded in an octahedral geometry to six equivalent N3- atoms. All Cr–N bond lengths are 2.11 Å. N3- is bonded in a distorted trigonal non-coplanar geometry to one Cr3+ and three H1+ atoms. There is two shorter (1.03 Å) and one longer (1.04 Å) N–H bond length. There are three inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom.
