Abstract

Abstract: A new ferrocene‐containing [Pd3 (L4EFc )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 (L4EFc ), 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 ⋅ 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. Abstract : A new ferrocene‐containing, redox active [Pd3 (L4EFc )6 ] 6+ (X − )6 (where X=BF4 − or SbF6 − ) double‐walled triangle has been synthesized quantitatively from the rotationally flexible 1, 1′‐bis(4‐pyridylethynyl)ferrocene ligand (L4EFc ).
