L<sup>†</sup>MnMg­(<sup>Mes</sup>Nacnac) (L<sup>†</sup> = −N­(Ar<sup>†</sup>)­(SiPr<sup><i>i</i></sup><sub>3</sub>), Ar<sup>†</sup> = C<sub>6</sub>H<sub>2</sub>{C­(H)­Ph<sub>2</sub>}<sub>2</sub>Pr<sup><i>i</i></sup>-2,6,4; <sup>Mes</sup>Nacnac = [(MesNCMe)<sub>2</sub>CH]<sup>−</sup>; Mes = mesityl). This compound has been utilized as an “inorganic Grignard reagent” in the preparation of the first two-coordinate manganese­(I) dimer, L<sup>†</sup>MnMnL* (L* = −N­(Ar*)­(SiMe<sub>3</sub>), Ar* = C<sub>6</sub>H<sub>2</sub>{C­(H)­Ph<sub>2</sub>}<sub>2</sub>Me-2,6,4), and the related mixed valence, bis­(amido)-hetereobimetallic complex, Mn<sup>II</sup>(μ-L<sup>†</sup>)­(μ-L*)­Cr<sup>0</sup>. It is also shown to act as a two-electron reducing agent in reactions with unsaturated substrates.
