Résumé:
This thesis work presents the synthesis and structural determination by single crystal X-ray
diffraction of mono and polynuclear coordination compounds of transition elements from the
first period 3dn divalent, copper and manganese. The structural studies and physicochemical of
these compounds were realized using several techniques: infrared spectroscopy, X-ray
diffraction, thermal analysis and magnetic properties of obtained complexes.
The synthesis and study of the structural and magnetic properties of new series of mon-, di, and
polymeric compounds resulting from the association of 2-thiopheneacetic acid ligand with the
neutral co-ligand, imidazole and benzimidazole, in the presence of the copper (II) ion, is the
topic of the second part. The study of their magnetic proprieties contributes to a better
understanding of the factors responsible for the nature and intensity of magnetic interactions.
Two other mono and polymeric complexes obtained, they are considered as the first compounds
resulting from the combination of the 2-thiophene acetic acid ligand with the manganese (II)
cation. In the last part, we describe the preparation of two new compounds based on
benzothiazole and aminothiophenol.
