The chirality of the ligand determines the nature of the helix : Coordination of a chain of [15]metallacrown‐5 complexes based on phenylalanine hydroxamic acid results in an amphiphilic metallohelix with a 4 1 screw axis. The use of the L isomer of the acid gives the right‐handed helix (see left structure) while the D isomer gives the mirror image structure.
