Here, we report a unique transformation from heterochiral to homochiral structures in ionic crystals composed of complex cations and complex anions. Treatment of an anionic AuCo complex, ΛΛ-[AuCo(d-pen)] ([]; Hpen = penicillamine), with M = Mn, Co, Ni, Zn in water in the presence of 1,10-phenanthroline (phen) commonly gave ionic crystals formulated as [M(phen)(HO)][Na(HO)][{M(phen)(HO)}()] (), in which [M(phen)(HO)] and [M(phen)(HO)] adopt Δ and Λ configurations, respectively. While , , and were all stable in each mother liquor, was converted to [Mn(phen)][]·phen () containing the Λ configurational [Mn(phen)] under the same conditions. showed a water adsorption capacity higher than that of , despite its lower porosity of crystal.
在此，我们报道了由复杂阳离子和复杂阴离子组成的离子晶体中从异手性结构到同手性结构的独特转变。在1,10 - 菲咯啉（phen）存在下，于水中用M = Mn、Co、Ni、Zn处理阴离子型金钴配合物ΛΛ - [AuCo(d - pen)] ([]; Hpen = 青霉胺)，通常会得到化学式为[M(phen)(HO)][Na(HO)][{M(phen)(HO)}()] ()的离子晶体，其中[M(phen)(HO)]和[M(phen)(HO)]分别采用Δ和Λ构型。虽然 、 和 在各自的母液中都很稳定，但 在相同条件下会转化为含有Λ构型[Mn(phen)]的[Mn(phen)][]·phen ()。尽管 的晶体孔隙率较低，但其水吸附能力高于 。
