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)<img src='http://nopr.niscair.res.in/jinfo/ijcafeb21.gif' border=0>CH₃][<img src="http://www.niscair.res.in/jinfo/equation143.gif" alt="" border="0" />CHR'COO] (where R = C₆H₅, p-ClC₆H₄, CH₃and R’ = CH(CH₃)C₂H_5,CH₂CH(CH₃)₂ and CH(CH₃)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.
