Charge transfer complexes of 3-amino-1,2,4-Triazole Schiff Bases with dinitro and trinitro benzenes IR, Hnmr, Uv-vis spectral and conductance studies

Charge transfer complexes of 3-amino-1,2,4-triazole Schiff bases with some dinitro and trinitro compounds were prepared and investigated applying IR, UV vis, 1H-NMR and ESR spectroscopy. The results revealed that complex formation takes place through pi-electron transfer only for the nonacidic or weak acidic acceptors, while with strong acidic acceptors the reaction takes place through both electron and proton transfer. The electrical properties for some CT complexes are investigated in the solid state and correlated with EA and IP. The mechanism of the conduction process in these complexes is also studied
