Abstract

     A Schiff base, N, N'-(4H-1,2,4-Triazole-3,5-Diyl) bis(4-Methoxy-2-Methylbenzamide) (L) ,  was synthesized via the condensation of (3,5-Diamino-1,2,4-Triazole) with (methyl 4-methoxy-2-methylbenzoate), along with three complexes: [Ni(L)Cl₂], [Fe(L)Cl₂]Cl, and [Co(L) Cl₂]Cl. The compounds were characterized by using NMR, MASS, FTIR, Elemental analyses, Magnetic susceptibility, and Molar electrical conductivity. Results showed that (L) acts as a polydentate ligand through its carbonyl and amine groups. FTIR spectra confirmed coordination of Fe, Ni, and Co with (O, N), while magnetic susceptibility indicated octahedral geometries with paramagnetic and diamagnetic properties (?eff =2.4, 0.36) for Fe and Co, respectively, while a square planar for Ni (?eff = 0.2). The stabilization effect of the polymer was investigated using the synthesized complexes by UV–Vis spectroscopy at wavelengths of 275 and 385 nm. The results showed that these complexes significantly enhanced the thermal stability of the polymer by increasing its decomposition temperature
