The (cAAC) 2 Mn complex (cAAC=cyclic alkyl(amino)carbene) features a linear two‐coordinate Mn center. The antiferromagnetic coupling of a radical electron, delocalized on two carbene C atoms, with the central Mn I having d 6 electronic configuration, mainly contributes to the S T = 3 / 2 ground state. Treatment of (cAAC) 2 Mn with H 2 at RT resulted in the addition of H atoms at both “carbene” C atoms, leaving the central Mn atom in the S T = 5 / 2 spin ground state.
