A cobalt aquo-hydroxo complex of a ditopic Schiff-base pyrrole–crown ether macrocycle has been prepared and forms a rigid Pacman-clefted structure that assembles through hydrogen-bonding into a hexagonal wheel motif in the solid state.

forming alkali, alkaline earth, and transitionmetalcomplexes that were characterised spectroscopically and crystallographically. While the conformationally flexible O5 donor set allows the formation of helical potassium salt structures, the transitionmetalcomplexes of all variants of these macrocycles invariably adopt wedged, Pacman-shaped structures in which the metal is bound in the pyrrole-imine N4
