• 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. The distinct σ‐hole at bromine on the bonding axis of BrCl is crucial to the formation and stabilization of polyinterhalides such as the tridecainterhalide monoanion [Cl(BrCl)6]−. In this interhalide, the central chloride ion is coordinated by six BrCl molecules in a slightly distorted octahedral fashion.
