Annotation

The syntheses of a new ligand: di (Furanyl Methylene hydrazono Ethyl) Benzene have been studied. Its structure has been proved by using spectroscopy methods such as IR, 13C NMR. Then, the complex will be synthesized by reactance the ligand with HgCh.

Key words: Furanyl, hydrazono, mercury.

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]

The absorbance values were as in the table:

Through the figures (1), (2) and the absorption values in the tables, we have obtained the required result.

Nmr spectroscopy:

The spectrum has been obtained for the ligand in CDCh, tables show the values of chemical shift for resulting singals:

Through the figures (1), (2) and the absorption values in the tables, we have obtained the required result.

Nmr spectroscopy:

The spectrum has been obtained for the ligand in CDCh, tables show the values of chemical shift for resulting singals:

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

benzene electrolyte hydrazono ethyl
