Enantioselective/Anion-Selective Incorporation of Tris(ethylenediamine) Complexes into 2D Coordination Spaces between Tripalladium(II) Supramolecular Layers with d-Penicillaminate

The formation of a cocrystallized coordination compound, [Pd3(d-pen)3]2·[M(en)3](ClO4)3 (d-H2pen = d-penicillamine; M = CoIII or RhIII), from [Pd3(d-pen)3] and [M(en)3](ClO4)3 is reported. In this compound, only the Δ-configurational [M(en)3]3+ cations were incorporated when its racemic (Δ/Λ) isomer was employed. Besides this enantioselective incorporation of complex cations, this compound was found to show the selective incorporation of ClO4− as the anion species.
