SYNTHESIS AND CHARACTERISATION OF SOME Pb(II) MACROCYCLIC COMPLEXES

Abstract

One hundred twenty complexes of Pb(II) of the type [ 1 10 Pb1 3   X2] (where X= Cl or Br or NO3 or CH3COO and 1 10 L1 3   = macrocyclic ligands derived from the condensation of trimesic acid or þthathalic acid or squaric acid with different aliphatic diamines in 2:2 molar ratio) have been synthesized and characterized by elemental analysis, molar conductivity, Infrared and XPS i.e. X-ray photoelectron spectra data. An octahedral geometry was also established for them
