Complete halogenation of decamethyl-1,12-dicarba-closo-dodecaborane(12) under radical halogenation conditions affords the title compound 1 in high yields (structure shown along the C[BOND]C axis of the carborane framework). This molecule introduces an important new concept for the modular construction of structurally well-defined molecular systems.
