A mixed-type of azametallacrown containing [Mn6(pnhz)6(DMF)4(H2O)2] and [Mn6(pnhz)6(DMF)2(H2O)4] constructed by a flexible pentadentate ligand

An unprecedented mixed-type of azametallacrown based on a flexible pentadentate N-propionyl end ligand was reported, which exhibits not only the completely different arrangement of the metal centers but also diverse geometric configurations of the N-terminal ligands, and which was further assembled into novel 3-D supramolecular structure via various intermolecular interactions.
