SYNTHESIS, CHARACTERIZATION OF SOME METAL COMPLEXES OF DIETHANOLAMINEDITHIOCARBAMATE AND (1,10-PHENATHROLINE)

A dithiocarbamate ligand; sodiumdiethanolaminedithiocarbamte Na(deadtc) is synthesized from the reaction of diethanolamine with cabondisulfide and sodium hydroxide.( phen)= 1,10-phenathroline . Addition of metal salts, gave complexes of the types: [M(deadtc)2 phen], where M = Fe(II), Co(II), Ni(II) and Cu(II). [M(deadtc)3] where M= Fe(III). The ligand (deadtc) behaves as a bidentate and coordinated to the metal ion centers either through the sulfur atom of its dithiocarbamate and or through the nitrogen atoms of the phenathroline. All the synthesized ligands and complexes are characterized by elemental analyses, conductivity, infrared, electronic spectra and susceptibility measurements. From the obtained data octahedral geometry for the complexes have been suggested.
