Abstract
A three‐dimensional x‐ray diffraction study of a single crystal of B9H13(CH3CN) has yielded the complete structure, including hydrogen atom positions. The nine boron atoms form an icosahedral fragment, like the arrangement in B10H14 with one boron atom missing. The structure is consistent with the present form of the topological theory of boron hydrides and ions in that it has two BH2 groups, and is related to an anticipated B9H14— ion in the same way that B10H12(CH3CN)2 is related to B10H14—2 ion. The crystals are monoclinic, in the space group P21/m, and have two molecules in a unit cell having parameters a=5.64, b=9.22, c=9.81 A and β=90°±30 min.Keywords
