A brimming bowl: The [12]MC-6 fluoro metallacrown (MC) shown in the picture is crystallized both as a metal-free wheel and in complex with Na+ or K+ ions. The magnetic and structural properties are only slightly altered upon metal complexation. Opposite faces of the molecule form bowl-shaped cavities, in which H2O or CH2Cl2 molecules are hydrogen-bonded to the F acceptors.
