Synthesis, Characterization and Conductivity Studies of Tetraphenylstibonium Halides and Trihalides

Abstract

A series of tetraphenylstibonium halides and tetraphenylstibonium trihalides compounds of type Ph₄SbX (X = F, Cl, Br, I) and Ph₄SbX₃ (X₃ = Br₃, IBr₂, ICl₂) have been synthesized as crystalline solids. The electrolytic conductivity measurement in acetonitrile show that Ph₄SbF is very weak, Ph₄SbCl and Ph₄SbBr are weak but Ph₄SbI is a strong electrolyte. All of the trihalides show strong electrotytic conductivity. The calculation of molar conductivity supports the experimental results. The conductometric titrations studies of Ph₄SbCl with ICl, Ph₄SbBr with Br₂ and IBr indicate that the trihalides Ph₄SbX₃ are formed readily in acetonitrile solution.
