Uranium(III)-carbon multiple bonding supported by arene δ-bonding in mixed-valence hexauranium nanometre-scale rings
Abstract
Owing to the propensity for uranium(III) compounds to undergo disproportionation, uranium-element multiple bonds involving uranium(III) oxidation states remain rare. Here the authors report hexauranium-methanediide rings that formally contain uranium(III)- and uranium(IV)-methanediides supported by alternating halide and arene bridges.
