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. Ni (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. Ni (II) metal complex was synthesized in methanolic media. Metal-to-ligand ratios were found to be 1:1 for complex. Conductivity measurements suggested that complex was non-electrolytes. Binuclear Ni (II) complex exhibited subnormal magnetic moments indicating the possibility of antiferromagnetic interaction through a possible super exchange mechanism. 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 octahedral geometry for Ni (II) complex was suggested.
