| الوصف: | In this paper, new metal ions complexes of [chromium (III), iron (III), cobalt(II), nickel(II), copper(II) and cadmium(II)] were prepared from mixed Schiff base ligands 1-(2-aminoethyl) pyrrolidine-2,5-dione ligand which was prepared form the reaction of the succinic anhydride with ethylenediamine then reacted with salicyaldehyde to form a new Schiff base ligand1-[2-(2-hydroxybenzylideneamino)ethyl]pyrrolidine-2,5-dione (HL 1 ) . The amino acid (glycine) was reacted with salicyaldehyde to form another new Schiff base ligand (2-hydroxybenzaldine)glycine (HL 2 ) . The two types of Schiff bases ligands (HL 1 ) , (HL 2 ) were mixed with some metal ions [(Cr +3 , Fe +3 , Co +2 , Ni +2 , Cu +2 and Cd +2 )] to obtain a new metal complexes. The Schiff base ligands were characterized by physic-chemical spectroscopic techniques such as: FT-IR Spectra, UV-Vis. Spectra, mass spectroscopy, 1 HNMR and microanalysis techniques (C.H.N). Which is indicated the purity of Schiff base ligands. The fragments of the prepared free Schiff base ligand (HL 1 ) were identified by mass spectrometer technique. The metal complexes were characterized by spectroscopic techniques such as: FT-IR Spectra, UV-Vis. Spectra, molar conductivity, magnetic moment and microanalysis techniques (C.H.N) and chloride ion percentage. All the analysis of ligands and their metal complexes were in good agreement with the theoretical values which indicated the purity of Schiff base ligands and their metal complexes. From the above data, the molecular structures for all the metal complexes were proposed to be octahedral. The values of magnetic moments showed that all metal complexes are paramagnetic except cadmium (II) complex which is diamagnetic. The values of molar conductivity also appeared that all metal complexes are non-electrolytic nature except iron (III) complex which is electrolytic. |
