A new ferrocene‐containing [Pd₃(L_4EFc)₆]⁶⁺(X⁻)₆ (C ⋅ BF₄ and C ⋅ SbF₆ where X=BF₄⁻ or SbF₆⁻) self‐assembled double‐walled triangle has been synthesized from the known, rotationally flexible, 1,1′‐bis(4‐pyridylethynyl)ferrocene ligand (L_4EFc), and characterized by ¹H, ¹³C and diffusion ordered (DOSY) NMR spectroscopies, high‐resolution electrospray ionization mass spectrometry (HR−ESI−MS), X‐ray crystallography and cyclic voltammetry (CV). The molecular structures confirmed that double‐walled triangle cage systems (C ⋅ BF₄ and C ⋅ SbF₆) were generated. C ⋅ BF₄ was shown to interact with the anionic guest, p‐toluenesulfonate. CV experiments revealed that the triangles were redox active, however addition of the guest did not influence the redox potentials.
