6 (I). The structure - determined by X-ray diffraction - and the spectroscopic data of 2,4,6,8,9,10-hexachloro-2,4,6,8,9,10-hexaboraadamantane are in agreement with the classical description as an organoborane, rather than as a molecule with a carborane framework. Substitution reactions are described. The bromo compound C

4B
6Br
6 can be prepared by heating Me

2 to 520°C.
