Introduction
Schiff bases, the compounds containing (-C=N-) group have gained special attention. A large number of Schiff bases are often used as ligands in coordination chemistry [1, C. 4].Hydrazones, a subdivision of azomethine family[2, C. 268]. Hydrazones are compounds have azomethine linkage (C=N-N=C) are well known for their wide spectrum biological application such as anti-viral [3, C. 72], anti-tuberculosis, anti-depressant [4, C. 4], anti-tumor[5, C. 57], anti-convulsant [6, C. 50], anti-malarial[7, C. 77].
Hydrazones complexes have nitrogen and also oxygen donor atoms [8, C. 55].
Results and discussion
The ligand preparation:
The ligand was prepared by two steps:
The first step:
Prepare the compound: [1,4 di (hydrazono Ethyl) Benzene]

According to the spectroscopy FT-IR turned out to bind to the nitrogen atom closest to the furfural and oxygen atom in furfural ring because, disappearance (C=N-N=C) and appearance (C=N)1,(C=N)2 .
Absorption due to (C=N)1,(C-O-C) shift to the lower wave number.
It was found through calcination process that mono nuclear complex and electrolyte
