| 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 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. |
