Abstract
A series of transition metal complexes of α‐bromo‐ and ω‐bromoacetoacetanilide semicarbazones (L1H2 and L2H2, respectively) were prepared. Characterization of these compounds has been carried out by elemental analyses, infrared, electronic, and 1H NMR spectra and magnetic studies. These studies revealed that the ligands behave as tridentate mono‐ or di‐anions.
