Abstract

SYNTHESIS, CHARACTERIZATION AND STRUCTURAL STUDIES OF N-(2-HYDROXYPHENYL)-2-[(2-AMINOPHENYLAMINO)] ACETAMIDE AND ITS ZN (II) COMPLEX

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.
