Synthesis and characterization of Ni (II)‎, Cu (II)‎, Co (II)‎, Cr (II)‎ and Fe (II)‎ metal complexes of new 1, 3, 4-triazole derivative

الملخص EN

A Schiff base of 1,3,4-triazole derivative have been synthesized by the reaction between 5-(4-methylphenyl)-1,3,4-oxadiazole-2-thiol and hydrazine in the presence pyridine as catalyst to yield the 4-amino-5-(4-methylphenyl)-4H-1,2,4-triazole-3-thiol which was treated with aromatic aldehyde to gave five member heterocyclic ring schiff base called 5-(4-methylphenyl)-4-[(pyridin-2-ylmethylidene)amino]-4H-1,2,4-triazole-3-thiol as di-dentate ligand.

The last compound reacted with hydrated metal chlorides NiCl2, CuCl2, CoCl3,CrCl3 and FeCl3 in presence of ethanol as solvent to yield 1,3,4-triazole complexes.

The structures of synthesized ligand and their complexes have been established on the basis of their spectral FTIR, Mass,1H-NMR, elemental analysis C,H,N as well as Molar conductance .The purity of the compounds was confirmed by TLC.
