This study aimed to synthesis and characterize hexadentate Schiff's base ligand with the general structure (H 2 L) containing nitrogen and oxygen donor atoms type (N 2 O 4). The ligand (N, N)-bis-(salicylidine)-1, 2-bis-(o-aminophenoxy) ethane (H 2 L) was prepared from the reaction of o-aminophenol with salicylaldehyde in an acidic medium and the precursor 2-(2-hydroxybenzylieneamino) phenol was obtained, this precursor was reacted with dichloroethane in alkali medium to obtain the ligand (H 2 L). The prepared ligand (H 2 L) is characterized by FT-IR, UV-Vis, 1 H-NMR spectra and. The ligand was reacted with some metal ions under reflux in methanol with (1: 1) ratio gave complexes of the general formula [M (L)], Where: M II= Fe, Zn, Cd and Hg. These complexes were characterized by atomic absorption, chloride content, IR, UV-Vis spectra, molar conductivity, HPLC, melting point, and biological activity were tested for some complexes of this ligand. The molar conductance showed that, all complexes are non-electrolyte. According to all these measurements. The proposed structures for (H 2 L) complexes were an tetrahedral geometry for Fe II, Zn II, Cd II and Hg II
