A series of [Pd2L4]4+(X− )4 metallosupramolecular architectures have been synthesised where X−  = , , OTf− , OMs−  or OTs−  and L = 2,6-bis(pyridin-3-ylethynyl)pyridine. These systems have been characterised by NMR, IR and UV–vis spectroscopies, mass spectrometry, elemental analysis and, in several cases, by X-ray crystallography. Using these solution- and solid-state methods, we have investigated the exohedral and endohedral interactions of various anions with these cationic assemblies.
