2，3，6，7，14，15-Hexamethyl-9，10-distibatriptycene(3)与溴反应生成3.2Br2的加合物4。X-射线结构分析和核磁共振氢谱研究表明，溴加合物4在结晶态和溶液中都形成了一个由四配位溴钛正离子部分R3SbR+和六角三溴硫硼酸根离子R3SbBr3-组成的分子内盐。
2,3,6,7,14,15-Hexamethyl-9,10-distibatriptycene (3) reacted with bromine to give an adduct 4 with the composition of 3.2Br 2 . X-ray structure analysis and 1 H NMR studies revealed that the bromine adduct 4 forms an intramolecular salt composed of a tetracoordinate bromostibonium ion moiety, R 3 SbBr + , and a hexacoordinate tribromostiborate ion moiety, R 3 SbBr 3 - , both in the crystalline state and in solution.
