Synthesis and spectral studies of zinc(II) and palladium(II) complexes of amide ligands derived from 2-aminopyridine

Abstract

A few complexes of Zn(II) and Pd(II) with N-(2-pyridyl)- 3-carboxypropanamide and N-(2-pyridyl)-2-carboxybenzamide derived from 2-aminopyridine have been prepared and characterised on the basis of elemental analysis, conductivity measurements, thermal and spectral (IR, ¹H NMR, UV /vis) studies. Molar conductivities indicate non-electrolytic behaviour of most of the complexes. Spectral studies show the coordination of Zn(ll) through amide oxygen and pyridine nitrogen atom, while in case of Pd(II), pyridine nitrogen atom alone coordinates. On the basis of these studies, probable structures of the complexes have been assigned.
