The First Structural Characterization of an Azoaromatic Radical Anion Stabilized by Dicopper(I) Coordination

The First Structural Characterization of an Azoaromatic Radical Anion Stabilized by Dicopper(I) Coordination

Double chelate coordination of [Cu(Ph3P)2]+ stabilizes the radical anion of 2,2′‐azobis(5‐chloropyrimidine), which exhibits a N–N bond length of 1.345(7) Å in the complex (see picture). This is consistent with a one‐electron reduced azo functionality.
