With its so‐called ufosan structure the [Bi 11 ] 3− ion is the first polycyclic bismuth polyanion. S. Dehnen and co‐workers show in their Communication on page 4704 ff. that its synthesis occurs by the surprisingly simple reaction of [K([2.2.2]crypt)] 2 (GaBi 3 ) with the pyridine solvent to yield [K([2.2.2]crypt)] 3 (Bi 11 ). The binary Zintl anion [GaBi 3 ] 2− decomposes under oxidative coupling of pyridine molecules and release of H 2 to form the [Bi 11 ] 3− species.
