Abstract
A new ferrocene-containing [Pd-3(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 H-1, C-13 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.
