Three icosahedral and three planar building blocks (C 2 B 10 carboranes and benzene rings, respectively) alternate in the novel macrocycle 1 . This contains a cavity that is surrounded by hydrogen atoms, of which six are bound to boron and three to carbon; this cavity thus offers potential guests an unusual environment. Such “cluster‐cycles” offer some scope for use as frameworks on which to hold bi‐ and trinuclear arrays of metal atoms.
