Organic-Inorganic Hybrid Complexes of Lead (II) of Sterically Demanding Heterocyclic β-diketones and Flexible N-Protected Amino Acids

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 Pb[RC(O)C:C(O)N(C 6 H 5 )N:CCH 3 ][C(O)C 6 H 4 C(O)NCHR'COO] (where R = C 6 H 5 , p-ClC 6 H 4 , CH 3 and R’ = CH(CH 3 )C 2 H 5, CH 2 CH(CH 3 ) 2 and CH(CH 3 ) 2 ) has been 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 have been characterized on the basis of physico-chemical and spectroscopic studies.
