triple-decker complexes with bridging tetramethylcyclopentadienyl
ligands were synthesized by the reaction of electrophilic metal fragments
with octamethylferrocene, Cp′2Fe (Cp′ = C5Me4H). The reaction of coordinatively unsaturated
ruthenium cations [(C5R5)Ru]+ (R
= H, CH3) with Cp′2Fe afforded purple-colored
heterometallic triple-decker complexes [(C5R5)Ru(μ-Cp′)FeCp′]+ by direct electrophilic
addition. Surprisingly, the analogous reaction with the coordinatively
unsaturated manganese cation [Mn(CO)3]+ and
Cp′2Fe produced a blue homometallic triple-decker
complex, [Cp′Fe(μ-Cp′)FeCp′]+, by ring abstraction and subsequent addition of the newly generated
cation [Cp′Fe]+ to an equivalent of Cp′2Fe. Three air-stable triple-decker complexes, [Cp′Fe(μ-Cp′)FeCp′]+ (2), [CpRu(μ-Cp′)FeCp′]+ (3), and [Cp*Ru(μ-Cp′)FeCp′]+ (4), have been characterized by NMR spectroscopy,
elemental analysis, and single-crystal X-ray diffraction.
