A pair of related [Fe4L4]8+ tetrahedral cages were synthesised differing only in the electronic nature of the face-capping ligand. Cage **1** is comprised of four ligands containing a central triazine ring, whilst cage **2** is analogous utilising a benzene core. The cages were structurally characterised using X-ray crystallography performed at the Australian Synchrotron, which showed the cages to be flexible and adaptable. Solution based host-guest interactions were investigated by NMR spectroscopy, revealing that the cages are discriminating and selective in their host-guest behaviour.
