The redox properties of all complexes were investigated by cyclic voltammetry. The bulky salfen-Bu-t(2) allows the preparation of a stable uranyl(V) complex, while a stable U(IV) bis-ligand complex is obtained from the salt metathesis reaction between [UI4(OEt2)(2)] and K(2)salfen. The reduction of the [U(salfen)(2)] complex leads to an unprecedented intramolecular reductive coupling of the Schiff-base ligand resulting in a C-C bond between the two ferrocene-bound imino groups.text::journal::journal article::research article
