Two configurationally stable, chiral anions (TRISPHAT, 1) behave as efficient hosts that control the configuration of a configurationally labile iron(ii) complex as the guest with high diastereoselectivity (>96 % de) upon ion pairing. The diastereoselectivity increases with decreasing solvent polarity.
