Abstract

A [Cu^II₁₆] wheel was isolated serendipitously from the reaction of acetylacetone dioxime with copper(II) chloride and lanthanide ions in a reaction initially designed to produce heterometallic 3d–4f cages. The ligand has been transformed in situ to three different forms, all found within the [Cu₁₆] wheel, with the original ligand completely absent.
