AbstractSlipped triple‐decker complexes with a bridging indenyl ligand, namely [Cb*Co(μ:η5:η6‐C9H7)CoCb*]+ (2, Cb* = C4Me4) and [Cb*Co(μ:η5:η6‐C9H7)Ru(C5R5)]+ (R = H, 5a; Me, 5b), have been synthesised by electrophilic stacking of [Cb*Co(η5‐C9H7)] (1) with [Cb*Co(MeCN)3]+ or [(C5R5)Ru(MeCN)3]+ (R = H, Me), respectively. A similar reaction of [(C5R5)Ru(η5‐C9H7)] (R = H, 3a; Me, 3b) with [Cb*Co(MeCN)3]+ affords the cations [(C5R5)Ru(μ:η5:η6‐C9H7)CoCb*]+ (R = H, 4a; Me, 4b), which are isomeric with 5a,b. Stacking of [Ru(η5‐C9H7)2] (7) with [Cb*Co(MeCN)3]+ or [Cb*CoI]x/TlBF4 gives the triple‐decker complex [(η5‐C9H7)Ru(μ:η5:η6‐C9H7)CoCb*]+ (8). Further reaction of 8 with [Cp*RuCl]4/TlBF4 unexpectedly affords the slipped tetra‐decker ruthenium complex [Cp*Ru(μ:η5:η6‐C9H7)Ru(μ:η5:η6‐C9H7)RuCp*]2+ (11). The structures of [4b][Co(η‐7,8‐C2B9H11)2] and [Cp*Ru(η6‐C9H7)] (6) have been determined by X‐ray diffraction, and the electrochemical behaviour of the complexes prepared has been studied.
