This study details the synthesis and characterization of an unprecedented two-coordinate, high-spin manganese(0) complex that incorporates an unsupported Mn–Mg bond, viz. L†MnMg(MesNacnac) (L† = −N(Ar†)(SiPri3), Ar† = C6H2{C(H)Ph2}2Pri-2,6,4; MesNacnac = [(MesNCMe)2CH]−; Mes = mesityl). This compound has been utilized as an “inorganic Grignard reagent” in the preparation of the first two-coordinate manganese(I) dimer, L†MnMnL* (L* = −N(Ar*)(SiMe3), Ar* = C6H2{C(H)Ph2}2Me-2,6,4), and the related mixed valence, bis(amido)-hetereobimetallic complex, MnII(μ-L†)(μ-L*)Cr0. It is also shown to act as a two-electron reducing agent in reactions with unsaturated substrates.
