Abstract
We report a rare redox-active Mn0 metalloradical [Mn(CO)3(Ph2B(tBuNHC)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 MnI/0 redox potentials that are modeled using the Born equation.
