Abstract
The condensation reaction of 3-amino-1,2,4-triazole (amitrol, 3-AT) with N-acetylisatin caused the opening of the indole ring and led to the formation of the new ligand (Z)-2-(1H-1,2,4-triazol-3-ylimino-2-(2-acetamido-phenyl)-N-(1H-1,2,4-triazol-3-yl) acetamide (1), while the reaction with isatin and bis(2,3-dioxoindolin-1-yl)mercury(II), (Hg(isatin)2) caused no ring opening and the Schiff base (Z)-3-(1H-1,2,4-triazol-3-ylimino) indolin-2-one (2), and the new mercury complex 2-(E)-3-(1H-1,2,4-triazol-3-ylimino)-2-oxoindolin-1-yl)((Z)-3-(1H-1,2,4-triazol-3-ylimino)-2-oxoindolin-1-l)mercury(II) (3) were formed. New complexes of Co(II), Ni(II), Cu(II), Pd(II) and Zn(II) ions with the two ligands (1) and (2) were prepared. The studied products were characterized by elemental analysis, NMR, IR, mass spectra and thermal analysis. In all the complexes the metal was coordinated to the nitrogen atoms of the triazole ring and to the azomethine group.
