Materials Data on B20H26O by Materials Project
(B3H4)2(BH)8B6H8OH2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of thirty-two boranediylradical molecules, eight hydrogen molecules, eight B3H4 clusters, and four B6H8O clusters. In each B3H4 cluster, there are three inequivalent B+1.20- sites. In the first B+1.20- site, B+1.20- is bonded in a distorted water-like geometry to two H1+ atoms. There is one shorter (1.19 Å) and one longer (1.40 Å) B–H bond length. In the second B+1.20- site, B+1.20- is bonded in a distorted water-like geometry to two H1+ atoms. Both B–H bond lengths are 1.28 Å. In the third B+1.20- site, B+1.20- is bonded in a distorted water-like geometry to two H1+ atoms. There is one shorter (1.19 Å) and one longer (1.40 Å) B–H bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one B+1.20- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one B+1.20- atom. In the third H1+ site, H1+ is bonded in an L-shaped geometry to two B+1.20- atoms. In the fourth H1+ site, H1+ is bonded in an L-shaped geometry to two B+1.20- atoms. In each B6H8O cluster, there are three inequivalent B+1.20- sites. In the first B+1.20- site, B+1.20- is bonded in a distorted water-like geometry to two H1+ atoms. There is one shorter (1.19 Å) and one longer (1.30 Å) B–H bond length. In the second B+1.20- site, B+1.20- is bonded in a 3-coordinate geometry to two H1+ and one O2- atom. Both B–H bond lengths are 1.41 Å. The B–O bond length is 1.37 Å. In the third B+1.20- site, B+1.20- is bonded in a water-like geometry to two H1+ atoms. There is one shorter (1.19 Å) and one longer (1.30 Å) B–H bond length. There are four inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one B+1.20- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one B+1.20- atom. In the third H1+ site, H1+ is bonded in an L-shaped geometry to two B+1.20- atoms. In the fourth H1+ site, H1+ is bonded in an L-shaped geometry to two B+1.20- atoms. O2- is bonded in a bent 150 degrees geometry to two equivalent B+1.20- atoms.
