description: B7H9(BH)2 crystallizes in the monoclinic P2_1/c space group. The structure is zero-dimensional and consists of sixteen boranediylradical molecules and four B7H9 clusters. In each B7H9 cluster, there are fourteen inequivalent B1- sites. In the first B1- site, B1- is bonded in a distorted single-bond geometry to one B1- and one H+0.82+ atom. The B–B bond length is 1.77 Å. The B–H bond length is 1.20 Å. In the second B1- site, B1- is bonded in a distorted single-bond geometry to one B1- and one H+0.82+ atom. The B–B bond length is 1.84 Å. The B–H bond length is 1.19 Å. In the third B1- site, B1- is bonded in a distorted water-like geometry to one B1- and two H+0.82+ atoms. The B–B bond length is 1.99 Å. There is one shorter (1.19 Å) and one longer (1.33 Å) B–H bond length. In the fourth B1- site, B1- is bonded in a distorted trigonal non-coplanar geometry to three H+0.82+ atoms. There are a spread of B–H bond distances ranging from 1.19–1.34 Å. In the fifth B1- site, B1- is bonded in a distorted water-like geometry to two H+0.82+ atoms. There is one shorter (1.19 Å) and one longer (1.33 Å) B–H bond length. In the sixth B1- site, B1- is bonded in a distorted 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 seventh B1- site, B1- is bonded in a distorted bent 120 degrees geometry to one B1- and two H+0.82+ atoms. The B–B bond length is 1.82 Å. Both B–H bond lengths are 1.37 Å. In the eighth B1- site, B1- is bonded in a 7-coordinate geometry to seven B1- atoms. There are a spread of B–B bond distances ranging from 1.78–1.98 Å. In the ninth B1- site, B1- is bonded in a distorted single-bond geometry to one B1- and one H+0.82+ atom.

In the eleventh B1- site, B1- is bonded in a distorted water-like geometry to one B1- and two H+0.82+ atoms. There is one shorter (1.19 Å) and one longer (1.33 Å) B–H bond length. In the twelfth B1- site, B1- is bonded in a distorted trigonal non-coplanar geometry to three H+0.82+ atoms. There are a spread of B–H bond distances ranging from 1.19–1.34 Å. In the thirteenth B1- site, B1- is bonded in a distorted water-like geometry to two H+0.82+ atoms. There is one shorter (1.19 Å) and one longer (1.33 Å) B–H bond length. In the fourteenth B1- site, B1- is bonded in a distorted 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. There are eighteen inequivalent H+0.82+ sites. In the first H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one B1- atom. In the second H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one B1- atom. In the third H+0.82+ site, H+0.82+ is bonded in a single-bond geometry to one B1- atom.
