The preparation and characterization of a whole family of hydrated ionic co‐crystals formed by both enantiopure l‐proline and racemic dl‐proline with LiX (X=Cl, Br, I) are reported. The chiral preference of the lithium cation for homochiral coordination, both in the formation of crystalline conglomerates (with Cl and Br) and racemates (with Cl and I), in which molecules of opposite chirality are confined to distinct crystal layers, is discussed. Dehydration processes for all hydrated crystals have also been investigated.

离子共晶形成作为固态手性拆分的途径

全家由两个对映体纯形成水合的离子共结晶的制备和表征升-脯氨酸和外消旋DL -脯氨酸用的LiX（X =氯，溴，I）被报告。讨论了在形成阳离子团块（含Cl和Br）和外消旋物（含Cl和I）时锂阳离子对手性配位的手性偏爱，其中手性相反的分子被限制在不同的晶体层中。还研究了所有水合晶体的脱水过程。
