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 Mn^I/0 redox potentials that are modeled using the Born equation.
