Abstract

The reduction of Mn{C(SiMe₃)₃}₂ with KC₈ in the presence of crown ethers yielded the d⁶, Mn(i) salts [K₂(18-crown-6)₃][Mn{C(SiMe₃)₃}₂]₂ and [K(15-crown-5)₂][Mn{C(SiMe₃)₃}₂], that have near-linear manganese coordination but almost completely quenched orbital magnetism as a result of 4s-3dz² orbital mixing which affords a non-degenerate ground state.
