Reduction of [U(Ts-Tol)(Cl)(mu-Cl)U(Ts-Tol)(THF)(2)] [2, Ts-Tol = HC-(SiMe2NAr%26apos;)(3); Ar%26apos; = 4-MeC6H4)] with KC8 in toluene afforded the new arene-bridged diuranium complex [{U(Ts-Tol)}(2)(mu-eta(6):eta(6)-C6H5-Me)] (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 10 pi-tetraanion.
