A solvated zinc analogue of the calomel-dication

Author affiliations


The synthesis and characterisation of the solvent-stabilized salt [Zn2(THF)6]2+[BAr4F]2 (1) is presented, which features the dizinc dication [Zn2]2+ as an analogue of the calomel dication [Hg2]2+. The labile tetrahydrofuran (THF) solvate molecules of 1 can be readily substituted by other ligands. Reaction with the strong donor ligand PMe3 (Me = CH3) leads to the Zn(II) complex [Zn(PMe3)4]2+[BAr4F]2 by disproportionation, while the π-acceptor-ligand phenylisocyanide (PhNC) gives the substitution product [Zn2(PhNC)6]2+[BAr4F]2 (2) with an intact Zn–Zn bond.
