Fulvalene as a platform for the synthesis of a dimetallic dysprosocenium single-molecule magnet.

ABSTRACT: The dinucleating fulvalenyl ligand [1,1',3,3'-(C₅ ^t Bu₂H₂)₂]^2- (Fv^tttt) was used to synthesize the dimetallic dysprosocenium cation [{Dy(η⁵-Cp*)}₂(μ-BH₄)(η⁵:η⁵-Fv^tttt)]⁺ (3) as the salt of [B(C₆F₅)₄]^- (Cp* = C₅Me₅). Compound [3][B(C₆F₅)₄] was obtained using a method in which the double half-sandwich complex [{Dy(BH₄)₂(THF)}₂(Fv^tttt)] (1) was reacted with KCp* to give the double metallocene [{Dy(Cp*)(μ-BH₄)}₂(Fv^tttt)] (2), followed
