Large (Mw > 10 kDa) heterometallic coordination cages with gyrobifastigium-like geometry are obtained by using metalloligands with sterically demanding Feᴵᴵ clathrochelate cores and four divergent pyridyl groups. Upon reaction with cis-blocked Ptᴵᴵ and Pdᴵᴵ complexes, MII8L₄ cages are formed. The gyrobifastigium geometry of these cages is in contrast to the barrel-like structures which are typically observed for metallasupramolecular assemblies with M₈L₄ stoichiometry.
