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.
