A new ferrocene‐containing [Pd 3 ( L 4EFc ) 6 ] 6+ (X − ) 6 ( C ⋅ BF 4 and C ⋅ SbF 6 where X=BF 4 − or SbF 6 − ) 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 1 H, 13 C 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 ⋅ BF 4 and C ⋅ SbF 6 ) were generated. C ⋅ BF 4 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.
