Abstrakt: We report a rare redox-active Mn 0 metalloradical [Mn(CO) 3 (Ph 2 B( t Bu NHC) 2 )] - (NHC = N-heterocyclic carbene) with countercations [K(2.2.2)crypt] + , [Na(2.2.2)crypt] + , or [Li(DME)(12-crown-4)] + (DME = 1,2-dimethoxyethane), all characterized via single crystal X-ray diffraction. Cyclic voltammograms reveal solvation-dependent Mn I/0 redox potentials that are modeled using the Born equation.
