Abstract

The reduction of UVI uranyl halides or amides by simple LnII or UIII salts forms highly symmetrical, linear, oxo-bridged trinuclear UV-LnIII-UV, LnIII-UIV-LnIII and UIV-UIV-UIV complexes or linear LnIII-UV polymers according to the stoichiometry and solvent choice. Reactions can be tuned to give one- or two-electron uranyl reduction. Some features of their reactivity and magnetism are discussed in the context of using a series of strongly oxo-coupled homo and heterometallic poly(f-block) chains to better understand fundamental electronic structure in the f-block.
