Two-step chiral transfer from d-penicillamine to metallosupramolecular ionic crystals†
Abstract
Treatment of a racemic RhIII4ZnII4 complex, (Δ)4/(Λ)4-[Zn4O{Rh(aet)3}4]6+ (aet = 2-aminoethanethiolate), with D-penicillaminate (D-pen) gave optically pure ionic crystals composed of (Λ)4-[Zn4O{Rh(aet)3}4]6+ and ΛD-[Rh(D-pen)3]3−via intramolecular and intermolecular chiral transfers from D-pen.
