Synthesis and characterization of lanthanide complexes of 2-acetylaminothiazole

Abstract

A few lanthanide complexes of 2-acetylaminothiazole of the type [Ln(acamth)₂Cl₂]Cl [where Ln =La(III), Pr(III), Nd(III), Sm(III), Eu(III), Gd(III), Tb(III) or Dy(III)] have been synthesized and characterized by infrared, electronic, emission, magnetic susceptibility, molar conductance and X-ray powder data. It is observed from the IR spectra that ring nitrogen and carbonyl oxygen interact with lanthanide ions. The electronic spectra and molar conductivity suggest coordination number six around the metal ions.
