Materials Data on B9H11N4 by Materials Project
B3H5(BH)3B3N4H3 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of twelve boranediylradical molecules, four B3H5 clusters, and four B3N4H3 clusters. In each B3H5 cluster, there are three inequivalent B+0.33+ sites. In the first B+0.33+ site, B+0.33+ is bonded in a water-like geometry to two H+0.82+ atoms. There is one shorter (1.19 Å) and one longer (1.31 Å) B–H bond length. In the second B+0.33+ site, B+0.33+ is bonded in a trigonal non-coplanar geometry to three H+0.82+ atoms. There are a spread of B–H bond distances ranging from 1.19–1.39 Å. In the third B+0.33+ site, B+0.33+ is bonded in a water-like geometry to two H+0.82+ atoms. There is one shorter (1.19 Å) and one longer (1.30 Å) B–H bond length. There are five inequivalent H+0.82+ sites. In the first H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one B+0.33+ atom. In the second H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one B+0.33+ atom. In the third H+0.82+ site, H+0.82+ is bonded in an L-shaped geometry to two B+0.33+ atoms. In the fourth H+0.82+ site, H+0.82+ is bonded in an L-shaped geometry to two B+0.33+ atoms. In the fifth H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one B+0.33+ atom. In each B3N4H3 cluster, there are three inequivalent B+0.33+ sites. In the first B+0.33+ site, B+0.33+ is bonded in a bent 120 degrees geometry to one N3- and one H+0.82+ atom. The B–N bond length is 1.51 Å. The B–H bond length is 1.19 Å. In the second B+0.33+ site, B+0.33+ is bonded in a bent 120 degrees geometry to two N3- atoms. There is one shorter (1.46 Å) and one longer (1.49 Å) B–N bond length. In the third B+0.33+ site, B+0.33+ is bonded in a bent 120 degrees geometry to one N3- and one H+0.82+ atom. The B–N bond length is 1.65 Å. The B–H bond length is 1.19 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a 4-coordinate geometry to three B+0.33+ and one H+0.82+ atom. The N–H bond length is 1.02 Å. In the second N3- site, N3- is bonded in a single-bond geometry to one N3- atom. The N–N bond length is 1.15 Å. In the third N3- site, N3- is bonded in a linear geometry to two N3- atoms. The N–N bond length is 1.22 Å. In the fourth N3- site, N3- is bonded in a distorted bent 120 degrees geometry to one B+0.33+ and one N3- atom. There are three inequivalent H+0.82+ sites. In the first H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one B+0.33+ atom. In the second H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one B+0.33+ atom. In the third H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one N3- atom.
