Abstract

A new set of organic-inorganic hybrid complexes of lead(II) of sterically demanding heterocyclic β-diketones and flexible N-protected amino acids of composition where R = C6H5, p-ClC6H4, CH3 and R’ = CH(CH3)C2H5, CH2CH(CH3)2 and CH(CH3)2 ) was generated by the reactions of freshly prepared lead isopropoxide with sterically demanding heterocyclic β-diketones (LH) and flexible N-protected amino acids (AH) in 1:1:1 molar ratio in refluxing dry benzene . These lead(II) complexes of mixed organic ligands were characterized on the basis of physico-chemical and spectroscopic studies.
