An investigation has been made on the structural characteristics of a class of salts of dipicrylamine with organic and inorganic cations. A general conclusion regarding the mechanism of salt formation, nature of bondings and molecular configurations of this class of salts has been suggested from the studies on infrared spectra of these salts. The main features of the spectra of all the salts are almost similar showing similar nature of bondings and molecular configurations for all the salts. In this class of salts either organic or inorganic cations are linked with dipicrylamine anion by van der Waals forces through oxygens of one of the nitro groups of the dipicrylamine. The nitro groups are twisted out of plane of the benzene rings.
