Synthesis and Characterization of Transition Metal Complexes of α‐Bromo‐ and ω‐Bromoacetoacetanilide Semicarbazones

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.
