Abstract The synthesis and structural properties of novel compounds, 5-Benzyl- 4-[3-(1H-imidazol-1-yl)propyl]-2H-1,2,4-triazol-3(4H)-ones (3a–c) have been described. These products were obtained by the reaction of ethyl 2-[1-ethoxy-2-(phenyl or substituted phenyl)ethylidene]hydrazinecarboxylates (1) and N-(3-aminopropyl)imidazol (2). The structures of compounds 3a–c have been inferred through UV–vis
