Useful connection: The self-assembly of four salen complexes of pentavalent uranyl ions by mutual coordination affords a tetrametallic complex that is highly stable toward disproportionation and hydrolysis, and shows an unambiguous antiferromagnetic coupling between the four oxo-bridged uranium centers (see picture; O red, U green). The first mixed-valent UV3/UVI compound has been selectively synthesized from this complex.
