UCo bond : Reduction of [U(Ts Xy )(Cl)(thf)] [ 1 ; Ts Xy =HC(SiMe 2 NAr) 3 ; Ar=3,5‐Me 2 C 6 H 3 ] with KC 8 in toluene afforded the new arene‐bridged diuranium complex 2 , whereas reduction of 1 in aliphatic hydrocarbons resulted in CN bond activation and formation of an imido‐aryl complex, which exhibits an unusual ferromagnetic interaction between the two uranium centers. The synthetic utility of 2 was demonstrated by the first synthesis of a UCo complex, [U(Ts Xy )Co(CO) 3 (PPh 3 )] ( 3 ).
