Abstract

<p>Constitution of 8,8'-μ-H<sub>2</sub>N(-O-)(1,2-C<sub>2</sub>B<sub>9</sub>H<sub>10</sub>)<sub>2</sub>-3-Co sandwich has been elucidated 17 years after its first synthesis, <i>via</i> high resolution NMR methods supplemented by mass spectrometry. The species gives relevant "oximes" with acetone and benzaldehyde and is quantitatively methylated to the <i>N</i>,<i>N'</i>-dimethyl derivative, which shows an interesting redox disproportionation to a triatomically bridged sandwich with a 8,8'-μ-O-CH=N(Me)- bridge between both ligands. Several other "peculiar" reactions of this dimethyl derivative are discussed. On reductive cleavage of the parent hydroxylamine the non-bridged 8-HO-8-H<sub>3</sub>N(1,2-C<sub>3</sub>B<sub>3</sub>H<sub>10</sub>)<sub>2</sub>-3-Co zwitterion is obtained. Mono-, di- and trimethylated derivatives of this non-bridged species are characterized.
