Abstract: Synthesis of Ni (II) Complexes with ligand 4- (2, 4-diaminobeenzaldimino) -3, 5-dimercapto-1, 2, 4-triazole (L) as [NiLX3]. H2O, X= Pyridine, pyridine-oxide, Morpholine and picoline. Ligand [L] is synthesized by the condensation of 3, 5-dimercapto-1, 2, 4-triazole and 2, 4-diaminobenzaldehyde. The complexes are synthesized by refluxing the ligand and Ni (II) in presence of base. The complexes are characterized by the elemental analyses, magnetic moment measurement, IR, and spectral data analyses. The physical measurements and spectral data analyses and interpretation show that the ligand act as bidentate and coordinated through Nand S of>NH-NH2andSH group ligand. The ligand is a schiffs base derivative. The complexes of ligand and Ni (II) analyses and the structures of the complexes suggested
