Introduction. Macrocyclic compounds have attracted increasing interest owing to their mixed soft-hard donor character, versatile coordination behavior and in the understanding of molecular processes. 1, 2 Macrocyclic metal complexes are of significant attention in terms of structural and coordination chemistry.

The research presented in this thesis lies within the area of coordination chemistry and the study of polynuclear metal complexes. More specifically, this project involves the synthesis and structural and magnetic (for some examples) characterisation of novel polynuclear d-block metal complexes, featuring either C3-symmetric tripodal Schiff base ligands or small tridentate : Sylvie Godfrin.Synthesis of Metal Complexes The metal(II) complexes were prepared as follows: Ethanol solution containing appropriate mass ( mmol) of each metal salt (MnCl H 2 O, CoCl H 2 O, NiCl H 2 O and CuCl H 2 O) was added gradually with stirring to ethanol solution containing Schiff base, HL, (Polynuclear transition metal complexes (clusters) attract the intense interest of the chemical community due to their relevance in many interdisciplinary scientific fields.
The presence of metal ions gives rise to properties such as magnetic and catalytic, and enables clusters to function as molecular materials.
