Abstract

The synthesis and characterization of three new hybrid metal halide hydrates in which mer-[Cr^IIICl₃(H₂O)₃]⁰ cocrystallizes alongside α-methylbenzylammonium chloride are described. The enantiomorphic crystals, ((R)-(+)-α-methylbenzylammonium)₂(mer-[CrCl₃(H₂O)₃])Cl₂ ((R)-1) and ((S)-(-)-α-methylbenzylammonium)₂(mer-[CrCl₃(H₂O)₃])Cl₂ ((S)-1), have C222₁ space group symmetry and show mirrored circular dichroism signals. The racemate, (rac-α-methylbenzylammonium)₂(mer-[CrCl₃(H₂O)₃])Cl₂ ((rac)-1), adopts a polar structure with Cm space group symmetry in which enantiomers are related by mirror planes within organic bilayers. Alongside detailed crystallography and magnetism of each compound, the optical properties of the mer-[Cr^IIICl₃(H₂O)₃]⁰ unit are revisited. Understanding the intermolecular forces that stabilize each of these crystal structures lends insights into crystal engineering methodologies for stabilizing noncentrosymmetric hybrid metal halides.

本文描述了 mer-[CrIIICl3(H2O)3]0 与 α-甲基苄基氯化铵共晶体的三种新型杂化金属卤化物水合物的合成和特性。对映体晶体（(R)-(+)-α-甲基苄基铵）2(mer-[CrCl3(H2O)3])Cl2（(R)-1）和（(S)-(-)-α-甲基苄基铵）2(mer-[CrCl3(H2O)3])Cl2（(S)-1）具有 C2221 空间群对称性，并显示出镜像圆二色性信号。外消旋物 (rac-α-甲基苄基铵)2(mer-[CrCl3(H2O)3])Cl2（(rac)-1）采用 Cm 空间群对称的极性结构，其中对映体通过有机双层膜内的镜面相互关联。除了详细介绍每种化合物的晶体学和磁学特性外，还重新探讨了 mer-[CrIIICl3(H2O)3]0 单元的光学特性。了解稳定这些晶体结构的分子间作用力，有助于深入了解稳定非中心对称杂化金属卤化物的晶体工程方法。
