A drum‐shaped cage built up from six carbon and six boron atoms is proposed for the structure of 2 based on the comparison of experimental and calculated NMR chemical shifts. The novel arachno carborane 2 was obtained upon treatment of bis(diethylboryl)ethyne ( 1 ) with an excess of tetraethyldiborane(6) [Eq. (a)].
