The results confirm that the molecule consists of a pentaborane(9) cage substituted at the apical boron atom, B(1), by a dichloroboryl group; the BCl 2 moiety is essentially free to rotate about the exo B–B bond. CopyCopied, CSID:34987102, (accessed 03:22, Nov 27, 2020) Stable pentaborane, B5H9, is one of the boron hydrides, a short, comparatively little studied series of extraordinary compounds for which a satisfactory elementary valence theory is lacking.
