We report a rare redox-active Mn0 metalloradical [Mn(CO)3(Ph2B(tBuNHC)2)]- (NHC = N-heterocyclic carbene) with countercations [K([2.2.2]cryptand)]+, [Na([2.2.2]cryptand)]+, or [Li(DME)(12-crown-4)]+, all characterized via single crystal X-ray diffraction. Cyclic voltammograms reveal solvation-dependent MnI/0 redox potentials that are modeled using the Born equation.
