Multicomponent Fe(II)-iminopyridine-based self-assemblies have been synthesized with variably sized internal functionality. Larger internal functions provide increased strain to the complex and confer diastereocontrol upon the assembly process. Complete diastereocontrol is possible upon the introduction of large achiral groups on the cavity interior.

Endohedral isomerism in model achiral and chiral La@CN systems.

Endohedral structures with La or La encapsulated in chiral (1,16)CN or achiral (1,4)CN diazafullerenes were studied at the B3LYP/G-31G*/SDD level. Two stable locations of La and La are possible in each cage but only with La@(1,16)CN can the two isomers coexist. We found that an AIM determined hapticity of the endohedral species selectively differentiates the systems.
