Sc II or mixed oxidation state Sc III /Sc I ? Reduction of the homoleptic Sc III complex [Sc(P 3 C 2 t Bu 2 ) 3 ] allows access to the subvalent [{Sc(P 3 C 2 t Bu 2 ) 2 } 2 ] complex (see picture), in which the metal centers are formally bivalent. DFT calculations support fomulation of the reduced species as a mixed oxidation state Sc III /Sc I complex.
