Abstract
In this work we aimed to preparation of some ligands derived from carboxylic acids and its complexes with some transition metals and study its biological activity.
The structures of the isolated complexes were proposed on the basis of elemental analysis (C, H, M, Cl), spectral (IR, UV-Vis., 1H-NMR, mass spectra), thermal (TGA, DTG) and magnetic moments.
The analyses of solid complexes and preparation of solutions were described. Finally, the working procedures and apparatus (conductance, IR, UV-Vis., 1H-NMR, magnetic moment and thermal measurements).
