Isolation of a TMTAA‐Based Radical in Uranium bis‐TMTAA Complexes

These sandwich complexes show remarkable stability towards air and moisture, even at elevated temperatures. Electrochemical studies show the uranium complex to be stable in three different oxidation states; isolation of the oxidized species revealed a rare case of a non-innocent TMTAA ligand.
