title: Salts of the two-coordinate homoleptic manganese(I) dialkyl anion [Mn{C(SiMe3)3}2](-) with quenched orbital magnetism.
abstract: The reduction of Mn{C(SiMe3)3}2 with KC8 in the presence of crown ethers yielded the d(6), 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-3dz(2) orbital mixing which affords a non-degenerate ground state.
