A C3 symmetric pentadecanuclear metallamacrocycle was obtained by the self-assembly of a pentadentate bridging ligand, N-phenylpropiolyl salicylhydrazide (H3L), and a manganese ion. The combination of a narrow Cα-Cβ region near the bridging domain and a bulky phenyl end away from the bridging domain as a steric domain induced clockwise twists in the cycle. The resulting macrocycle with a sextuple twisted Möbius topology was stabilized by extensive weak intramolecular interactions.
