• Retrosynthetic analysis of a [M L ] coordination cage shows how it can be assembled rationally, in a stepwise manner, using a combination of kinetically inert and kinetically labile components. Combination of the components of -[Ru(L ) ](PF ) , Cd(BF ) and L in the necessary 4 : 12 : 12 stoichiometry afforded crystals of [Ru Cd (L ) (L ) ]X (X = a mono-anion) in which the location of the two types of metal ion [Ru(ii) or Cd(ii)] at specific vertices in the metal-ion array, and the two types of bridging ligand (L and L ) along specific edges, is completely controlled by the synthetic strategy. The incorporation of four different types of component at pre-determined positions in a coordination cage superstructure represents a substantial advance in imposing control on the self-assembly of complex metallosupramolecular entities.
