AbstractThe reaction of the diimine ligand 1,2-bis(1,3-diisopropyl-4,5-dimethylimidazolin-2-imino)ethane (BLiPr) with tetrameric [Cp*RuCl]4 in a 1 : 0.75 ratio afforded the complex salt [1][2] containing the 16-electron half-sandwich cation [Cp*Ru(BLiPr)]+ (1) and the dinuclear anion [Cp*Ru(μ- Cl)3RuCp*]− (2). The X-ray crystal structures of [1][2]·31/2THF (monoclinic, space group P21/n, Z = 4) and of [1][2]·THF (monoclinic, space group C2/m, Z = 4) are reported, allowing the structural characterization of the unprecedented anion 2, in which two [(η5-C5Me5)Ru(II)] moieties are bridged by three μ2-chlorine atoms.
