Synthesis and Characterization of a Two‐Coordinate Manganese Complex and its Reaction with Molecular Hydrogen at Room Temperature

Abstract

The (cAAC)2Mn 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 MnI having d6 electronic configuration, mainly contributes to the ST=3/2 ground state. Treatment of (cAAC)2Mn with H2 at RT resulted in the addition of H atoms at both “carbene” C atoms, leaving the central Mn atom in the ST=5/2 spin ground state.
