We report on helical coordination networks that were prepared using a hexanuclear manganese metallamacrocycle as a helical tecton. We were able to prepare the three-dimensional helical coordination networks using a hexanuclear manganese metallamacrocycle, [Mn6(lshz)6], as a helical tecton, where N-lauroyl salicylhydrazide (H3lshz) was used as the primary building unit to generate the helical tecton as a secondary building unit. While the 41/43 screw symmetry-linked helical coordination network was obtained when the primary building units had an N-acetyl group, both the 31/32 screw symmetry-linked and the 41/43 screw symmetry-linked helical coordination networks were obtained simultaneously in the same batch when the primary building unit had a long alkyl N-lauroyl group at the N-acetyl site.
