Abstract
A new polydentate ligand N-(2-hydroxyphenyl)-2-[(2-
aminophenylamino)] acetamide, (HPAPAA) has been synthesized in
the reaction between N-(2-hydroxyphenyl)-2-chloroacetamide and ophenylenediamine.
Zn (II) complex of the ligand was synthesized and
characterized on the basis of their spectral (IR, NMR, UV-Vis, and
AAS), elemental analyses, conductivity and magnetic susceptibility
measurements. Zn (II) metal complex was synthesized in methanolic
media. Metal-to-ligand ratios were found to be 1:1 for complexes.
Conductivity measurements suggested that complex was nonelectrolytes.
The ligand behaves as dibasic tridentate, employing ONO
donor sequence in chelation including phenoxide bridging. Based on
the analytical, infrared, conductivity, magnetic susceptibility and electronic spectral data it
may be concluded that square planar geometry for Zn (II) complex was suggested.
Keywords: Polydentate ligand, Zn (II) complex, HPAPAA.
