Synthèse, étude structurale et propriétés physiques des complexes à base de ligands soufrés et métaux de transition. / Hasna Bouchareb  

Public ISBD Titre : Synthèse, étude structurale et propriétés physiques des complexes à base de ligands soufrés et métaux de transition. Type de document : texte imprimé Auteurs : Hasna Bouchareb, Auteur ; M'hamed Boudraa, Directeur de thèse Editeur : جامعة الإخوة منتوري قسنطينة Année de publication : 2017 Importance : 192 f. Format : 30 cm. Note générale : 2 copies imprimées disponibles Langues : Français (fre) Tags : Sulfur ligands  Co-ligand  Coordination compound  Structural determination  X-ray diffraction  Magnetics interactions  Ligands soufrés  Composés de coordination  Etude structurale  Diffraction des rayons X  Interactions magnétiques Index. décimale : 540 Chimie et sciences connexes 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.

Synthèse et etude structurale des complexes à base des Métaux de transition et des dérivés de la sulfanilamide / Sabrina Benmebarek  

Public ISBD Titre : Synthèse et etude structurale des complexes à base des Métaux de transition et des dérivés de la sulfanilamide Type de document : texte imprimé Auteurs : Sabrina Benmebarek, Auteur ; M'hamed Boudraa, Directeur de thèse Editeur : جامعة الإخوة منتوري قسنطينة Année de publication : 2017 Importance : 182 f. Format : 30 cm. Note générale : 2 copies imprimées disponibles Langues : Français (fre) Tags : Sulfanilamide ligands  solvent  co-ligand  transition metal complex  X-ray diffraction  thermal decomposition  Ligands sulfanilamide  solvant  complexe de métaux de transition  diffraction RX  décomposition thermique Index. décimale : 540 Chimie et sciences connexes Résumé : Given to the ability of the derived sulfonamide to coordinate with the metal atoms in various ways, considerable interest in synthesis and structural characterization aspects of new complexes has appeared. In this work, we based on the chemical ability of the sulfonamide ligand to act by these two functions: the function -S(O)2N(H)- and the aromatic amino function -NH2 led us to characterize the original complexes based on sulfanilamide ligand. A zinc-based mononuclear complex and a molybdum-based polymer, characterized by X-ray diffraction, infrared spectroscopy and TG thermogravimetric analysis, carried out by studying hydrogen bonds. Two other polymer complexes of cobalt and copper, characterized by X-ray diffraction, carried out by the study of hydrogen bonds. Three other organic compounds of nitro benzene sulphynil in the ortho position have been characterized by X-ray diffraction, generates the study of the interactions, graphs and models of the hydrogen bonds.
