Comproportionation reactions between MnCl2 and KMnO4 in the presence of arsonate or phosphonate ligands promote the cationassisted assembly of high-nuclearity, wheel-shaped or toroidal {Mn8} (1) and {Mn24} (2) complexes; the closely corresponding reaction systems provide insights into the complexation behaviour of homologous phosphonate/arsonate ligand species.
