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-butoxyanilinThe 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 Zincpowder.The ligand was reacted with some metal ions in the presence of ethanol as a solvent2:1 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=0All compounds have been characterized by spectroscopic ( I.R,U.V.Vis. ) metalcontent, melting point and molar conductivity measurement, which showed that thecomplexes are non-electrolyte .The proposed geometry for complexes were Mn,Co octahedralwhile Cu have been square planer . Finally Zn .Ni complexes a tetrahedral geometry .
