✦ Synopsis


The structure of ions and ion pairs of Meisenheimer and Janovsky o-complexes of 1,3,5trinitrobenzene has been studied by derivative spectroscopy and semiempitical quantum chemical PM3 and CNDO/S methods. On the base of comparison of theoretical and experimental electronic absorption spectra the three types of co-ordination of anion and cation have been defined. It was established that the structure of ion pairs is determined by the nature of the subsituents of the pyramidal unit.
