Die Ionisation von Triphenylchlormethan durch Metallchloride in Acetonitril

In acetonitrile (AN) solutions the gross constants are determined for the reactions $$Ph_3 CCl + MCl_n ANPh_3 C^ + MCl_{n + 1}^ - + AN$$ (MCl _n =SbCl₅, GaCl₃, InCl₃, and FeCl₃). The relaxation spectra are interpreted for the reactions of metal(III) chlorides according to the equilibria $$\begin{gathered} 2 MCl_3 AN + 6AN \rightleftharpoons MCl_2 (AN)_4 ]^ + MCl_4 ]^ - + 4 AN \rightleftharpoons \hfill \\ 2 MCl_2 (AN)_4 ]^ + Cl - \hfill \\ \end{gathered} $$
