The bromine‐chlorine dianionic octahalide‐containing salts [C3(NEt2)3]2[Br4Cl4] (1c) and [C3(NEt2)3]2[Br3Cl5] (2d) were prepared using the triaminocyclopropenium cation as a template. The salt 1c was prepared in two steps, firstly, either by addition of BrCl to the triaminocyclopropenium chloride salt [C3(NEt2)3]Cl or addition of Cl2 to the bromide salt [C3(NEt2)3]Br to form the trihalide [BrCl2]– salt, secondly, addition of half an equivalent of Br2 gave the desired product upon crystallization at low temperature. Salt 2d is prepared by addition of excess BrCl to [C3(NEt2)3]Cl. Both salts are best described as two trihalides bridged by a dihalogen. When the tetraethylammonium cation is used, a salt of the formula [NEt4]2[Br4.56Cl0.44][ClBr2] (4), containing disordered [ClBr2]– and a chain of [ClBr4]– and [Br5]– pentahalides (in a ratio of 0.44 to 0.56, respectively). These interhalides were characterized by X‐ray crystallography, computational studies, Raman and Far‐IR spectroscopy, as well as by TGA and melting point.

溴-氯互卤化物[Br3Cl5] 2 –，[Br4Cl4] 2–和[Br6.56Cl1.44] 2–
制备了含溴-氯双阴离子八面体的盐[C 3（NEt 2）3 ] 2 [Br 4 Cl 4 ]（1c）和[C 3（NEt 2）3 ] 2 [Br 3 Cl 5 ]（2d）以三氨基环丙烯阳离子为模板。盐1c分两步制备，首先，将BrCl添加到三氨基环氯化en盐[C 3（NEt 2）3 ] Cl中，或添加Cl 2往溴化物盐[C 3（NEt 2）3 ] Br中形成三卤化物[BrCl 2 ] -盐，其次，在低温下结晶时，加入一半当量的Br 2得到所需的产物。盐2d通过将过量的BrCl添加到[C 3（NEt 2）3 ] Cl中来制备。最好将两种盐描述为由二卤素桥接的两个三卤化物。当使用四乙铵阳离子时，式[NEt 4 ] 2 [Br 4.56 Cl 0.44 ] [ClBr 2 ]（4的盐），含有无序[ClBr 2 ] -以及一串[ClBr 4 ] -和[Br 5 ] -五卤化物（比率分别为0.44至0.56）。这些卤化物的特征在于X射线晶体学，计算研究，拉曼光谱和远红外光谱以及TGA和熔点。
