Abstract

Chiral recognition behavior of the anionic Au^I₃Co^III₂ complex with D-penicillaminate (D-pen), [Au₃Co₂(D-pen)₆]³⁻ ([1]³⁻), toward the cationic Co^III₃ and Co^III₄Zn^II₄ complexes with 2-aminoethanethiolate (aet), [Co₃(aet)₆]³⁺ ([2]³⁺) and [Co₄Zn₄O(aet)₁₂]⁶⁺ ([3]⁶⁺), on crystallization is reported. Treatment of Na₃[1] with the racemic (Δ)₂/(Λ)₂-[2](NO₃)₃ and (Δ)₄/(Λ)₄-[3]Br₆ gave ionic crystals of [2][1] (I) and [3][1]₂ (II), respectively. Single-crystal X-ray crystallography revealed that [1]³⁻ anions form hydrogen-bonded frameworks with different chiral pockets that are best fitted for the accommodation of [2]³⁺ and [3]⁶⁺ cations in I and II, respectively. While both the (Δ)₂ and (Λ)₂ isomers of [2]³⁺ were equally incorporated in I, only the (Δ)₄ isomer of [3]⁶⁺ was selectively incorporated in II.
