Abstract

The silsesquioxane ligand (ⁱBu)₇Si₇O₉(OH)₃ (^iBuPOSSH₃) is revealed as an attractive system for the assembly of robust polynuclear complexes of uranium(III) and allowed the isolation of the first example of a trinuclear U(III) complex ([U₃(^iBuPOSS)₃]) that exhibits magnetic communication and promotes dinitrogen reduction in the presence of reducing agent.
