Dicationic triple-decker complexes with a bridging boratabenzene ligand

New dicationic triple-decker complexes with a bridging boratabenzene ligand [Cp*Fe(μ-η:η-C5H5BMe)ML]X2 (ML=CoCp*, 6(CF3SO3)2; RhCp, 7(BF4)2; IrCp, 8(CF3SO3)2; Ru(η-C6H6), 9(CF3SO3)2; Ru(η-C6H3Me3-1,3,5), 10(CF3SO3)2; Ru(η-C6Me6), 11(CF3SO3)2) were synthesized by stacking reactions of Cp*Fe(η-C5H5BMe) (2) with the corresponding half-sandwich fragments [ML]2+. The structure of 10(CF3SO3)2 was determined by X-ray diffraction study.
