Abstract

Reduction of [U(TsTol)(Cl)(μ-Cl)U(TsTol)(THF)2] [2, TsTol = HC(SiMe2NAr′)3; Ar′ = 4-MeC6H4)] with KC8 in toluene afforded the new arene-bridged diuranium complex [{U(TsTol)}2(μ–η66-C6H5Me)] (3); combined structural, spectroscopic, magnetic, and computational analyses unambiguously confirm that the uranium centres in 3 are in the +5 oxidation state and the toluene is a 10π-tetraanion.
