Synthesis and Characterization of New Bidentale Ligand type (NO) [2- hydroxy -4- butoxy aniline] and its Complexes with Metal ion MnII, CoII , NiII, CuII and ZnII

Abstract

The aim of this work is the synthesis and characterization of the new ligand (HL) containing (N and O) as donar atoms where : HL = 2-hydroxy -4-n-butoxyanilin The preparation of ligand includes two steps. Reaction of para Nitro phenol with n- Bromobutan in 1:1mole Raito. the second step is adding ammonium chloride and Zinc powder.The ligand was reacted with some metal ions in the presence of ethanol as a solvent 2:1 mole ratio to give the complexes in general formula [M(L)2(H2O)n] where : M = Mnп , Coп , n=2; M= Niп , Cuп , Znп n=0 All compounds have been characterized by spectroscopic ( I.R,U.V.Vis. ) metal content, melting point and molar conductivity measurement, which showed that the complexes are non-electrolyte .The proposed geometry for complexes were Mn,Co octahedral while Cu have been square planer . Finally Zn .Ni complexes a tetrahedral geometry.
