Triangular or pyramidal? Solvent‐induced divergent self‐assembly of a chiral ligand and Pr III ions leads diastereoselectively to two distinct but related superstructures, in which the ligands form helical domains attached to triangular (Pr 3 ) or pyramidal (Pr 4 ) metallic scaffolds (Pr green). The two structures are reversibly interconverted simply by varying the amount of water present in the solvent (CH 3 CN).
