R2Bi−BiR2 [1; R = 2,6-(Me2NCH2)2C6H3], a dibismuthane that exists in different forms in the crystalline state, reacts in air with the formation of the peroxide [R2Bi]2(O2) (2) and partial oxidation of the pendant (dimethylamino)methyl groups, yielding the mononuclear bismuth complex R‘R‘ ‘Bi (3) [R‘ = 2-(Me2NCH2)-6-{Me2N(O)CH2}C6H3; R‘ ‘ = 2-(Me2NCH2)-6-{O(O)C}C6H3].
