Synthesis and Spectral Investigation of La(III), Ce(III), Pr(III), Nd(III) and Sm(III) Coordination Chain Polymeric Assemblies

The coordination chain polymers of La(III), Ce(III), Pr(III), Sm(III) and Nd(III) with N,N′‐di(o‐carboxyphenyl)terephthalaldehydediimine have been prepared. The characterization of these newly synthesized coordination chain polymers were done by elemental analysis, magnetic measurements, infrared spectra, reflectance spectral studies and thermogravimetric analysis. The Schiff base acts as a dinegative tetradentate ligand and bonding through the oxygen and nitrogen atoms. The insolubility of the coordination chain polymers in common organic solvents suggest their polymeric nature.
