Abstract

A series of Pb(II) complexes of the type Pb(L)2 have been synthesized with fluorinated Schiff bases derived from 3-methyl-4-fluoroacetophenone and amino acids (viz phenylalanine, alanine, tryptophan, valine, isoleucine, and glycine). These complexes are insoluble in common organic solvents but soluble in DMF and DMSO. The measured molar conductance values in DMF indicate that the complexes are non-electrolytes. On the basis of analytical and spectral (IR, UV–visible, and 1H, 13C and 19F NMR) studies, it has been concluded that all the metal complexes have square planar geometry in which the ligand is coordinated to the metal ion through the azomethine nitrogen atom and the carboxylate oxygen atom via deprotonation.
