New connections for old borane cages: Oxidation of suitable precursors in which two decaborate cages are linked in an apical–equatorial fashion provides the borane ions 1 and 2 . The two nonequivalent cage fragments are cis ‐linked, in contrast to the trans ‐[B 20 H 18 ] 2− ion that has been known for over 30 years. Reductive substitution of 1 and 2 leads to new apical–apical linked anions and disubstituted [B 20 H 18 ] anions. •=B, ○=BH.
