Résumé:
This thesis work presents the synthesis, the structural study by spectroscopic methods,
X-ray diffraction, magnetic and photoluminescent properties of new transition metal
complexes using the two ligands 2-(2-aminophenyl) benzimidazole (2-ampb) and 4-
(dimethylamino) pyridine (DMAP).
Five mono, di and polynuclear coordination complexes based on copper (II) and
cadmium (II) were obtained with 2- (2-aminophenyl) benzimidazole ligand:
* ([Cu(C13H11N3)(NO3)2(H2O)2].H2O), (I).
* ([Cu(C13H11N3) (Cl)2]2), (II).
* ([[Cu(C13H11N3)2(H2O)2]2+, 2Cl-]. H2O), (III).
* ([Cd(C13H11N3)2(NO3)2],CH3OH), (IV).
* [Cd2(C13H11N3)2(CH3COO)4]n, (V).
The study of their magnetic proprieties contributes to a better understanding of the
factors responsible for the nature and intensity of magnetic interactions.
With the 4-(dimethylamino) pyridine ligand, we have obtained three new mono and
polynuclear coordination complexes with cobalt (II) and zinc (II):
* ([Co(C7H10N2)2(N3)2]n), (I).
* ([(C7H11N2)[CoCl3- (C7H10N2)]), (II).
* ([Zn(N3)2(C7H10N2)2]), (III).
