• Metallacrown
• Diversely geometric configuration
• Mixed-type of azametallacrown
• Supramolecular structure

A mixed-type of azametallacrown based on a flexible pentadentate N-propionyl ligand was reported, which exhibits not only the completely different arrangement of the metal centers but also diversely geometric configurations of the N-terminal ligands, and this complex can further assemble into a novel 3-D supramolecular structure using two different aza18-MC-6 as secondary building units (SBUs) via the intermolecular C-H center dot center dot center dot pi, pi-pi and C-H center dot center dot center dot O interactions. Temperature-dependent magnetic susceptibility measurements of the title complex indicate that the complex presents significantly antiferromagnetic coupling among metal centers.
