Synthesizing New Complexes Using [HPEBH=4-Hydroxy-N'-(1-(Pyridine-2-yl) ethylidene) Benzohydrazide)]

Abstract

In this study, a new ligand [HPEBH=4-Hydroxy-N'-(1-(Pyridine-2-yl) ethylidene) Benzohydrazide)], and it's transition metal complexes with [Ni^II, Co^II, and Cu^II ] were synthesized.The synthesis of ligand (HPEBH) was carried by the condensation of 1-(Pyridine-2-yl)ethan-1-one with 4-HydroxyBenzohydrazone .Then, the reaction of this ligand with Cobalt (II), Nickel (II), Copper (II) ions were carried out using metal chloride salt by the (2:1) molar ratio, fowr new mononuclear. complexes were obtained which have the formula [M(HPEBH)₂] ; M= Ni^II , Co^II, Cu^II The structures of the ligand and it's complexes were elucidated by FT-IR , U.V.–visible .

Keywords: hydrazone, azometine, pyridine, metal complexes.
