    Abstract: A novel polydentate ligand,L= 2,2'-bipyridyl-6,6' bis(2-acetylpyrazinohydrazone), was synthesized by condensation of 6,6'-dihydrazine-2,2' bipyridine and 2-acetylpyrazine. Reaction of Lligand strands with nickel(II) perchlorate in CH3 CN generates a double helical dinuclear complex. Its complexation behavior was studied by UV-Vis spectrophotometric titration experiments that revealed the formation of dinuclear complexes [Ni2L2](ClO4)4. Moreover, the double-helical structure of [Ni2L2](ClO4)4 was confirmed by X-ray diffractometer. Each nickel(II) center occupies a distorted octahedral environment. Variable temperature magnetic measurements revealed weak antiferromagnetic interactions between Ni(II)ion centers with J = -0.34 cm-1.
