Isomers of a dibismuthane, R2Bi-BiR2 [R=2,6-(Me2NCH2)(2)C6H3], and unusual reactions with oxygen: Formation of [R2Bi](2)(O-2) and R' R'' Bi [R'=2-(Me2NCH2)-6-{Me2N(O)CH2}C6H3; R''=2-(Me2NCH2)-6-{O(O)C}C6H3]
R2Bi-BiR2 [1; R = 2,6-(Me2NCH2)(2)C6H3], a dibismuthane that exists in different forms in the crystalline state, reacts in air with the formation of the peroxide [R2Bi](2)(O-2) (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].
