Due to a more distinct σ‐hole, BrCl is able to form stronger halogen bonds than those in polyhalogen anions based on Cl₂ and Br₂. This stabilization allows the crystallographic characterization of a variety of new polyinterhalides, in which chloride functions as the central ion as shown by the molecular structures of [AsPh₄][Cl(BrCl)₃] and [CCl(NMe₂)₂][Cl(BrCl)₅]. Furthermore, the solid‐state structure of an octahedrally coordinated nonclassical interhalide is reported for the first time. The tridecainterhalide monoanion [Cl(BrCl)₆]⁻ consists of a central chloride ion, which is coordinated by six BrCl molecules in a slightly distorted octahedral structure. All new compounds were characterized by single‐crystal X‐ray diffraction (XRD), NMR and Raman spectroscopy, as well as quantum‐chemical calculations.

基于一氯化溴的非经典卤化物的合成与表征

由于存在更独特的σ孔，因此与基于Cl ₂和Br _2的多卤素阴离子相比，BrCl能够形成更强的卤素键。这种稳定作用使得可以对各种新型的聚卤化物进行晶体学表征，其中氯化物起着中心离子的作用，如[AsPh ₄ ] [Cl（BrCl）₃ ]和[CCl（NMe ₂）₂ ] [Cl （BrCl）₅ ]。此外，首次报道了八面体配位的非经典卤化物的固态结构。十三间卤化物单阴离子[Cl（BrCl）₆ ] ^-由一个中央氯离子组成，该氯离子由六个略呈扭曲的八面体结构的BrCl分子配位。所有新化合物都通过单晶X射线衍射（XRD），NMR和拉曼光谱以及量子化学计算来表征。
