Abstract:
1. 2 - (2 - aminoethyl)isoindoline - 1,3 - dione has been prepared from the reaction of the isobenzofuran - 1,3 - dione with 2 aminoethanaminium and the product was reacted with from Salicyaldehydeto to from Schiff base ligand (2 - (2 - (2 - hydroxy benzylideneamino) ethyl) isoindoline - 1,3 - dione (HL1). 2. (Z) - 4 - (2 - hydroxybenzylideneamino) - 1,5 - dimethyl - 2 - phenyl - 1H - dimethyl - 1 - phenyl - 3 - pyrozoline - 5 - on.the product was reactedwith salicylaldehyde to form Schiff base ligand(HL2).3. Awide range of new metal ions : (Cu(II), Ni(II),Co(II), Cr(III), Fe(III), Cd(II), Pd(II), VO(II), Hg(II), Mn(II),Re(V) and Zn(II)) complexes have been prepared from mixed ligands and characterized by Infrared , electronic absorption spectra ,thermal analysis,Elemental micro analysis, Mass spectra, molar conductivity, quantitative analysis of the metal ,magnetic measurements and chloride contents .4. The results showed the formation and the high purity of the free Schiff bases ligands and their metal complexes ,indicating that they are in a good agreement with the theoretical values . The fragments of the prepared free Schiff bases ligands are identified by mass spectrometer techniques in additional to IR , Electronic spectra and C.H.N . All the analysis of ligands are in good agreement with the theoretical values which indicated the purity of Schiff bases ligand 5. The thermo gravimetric analysis of Chromium (III),Ferric(III)and Rhenium (V) complexes were carried out at Laboratories of Ibn - AI - Haitham,University of Baghdad result showed were in a good agreement with the calculated values.7. The values of magnetic moment are showed that all the prepared metal complexes are paramagnetic except the(g(II),Cd(II),Zn(II) and Pd(II)) complexes are diamagnetic.6. From the above data ,the molecular structures for all the metal complexes were proposed to be octahedral excepted Palladium is square planar and Copper tetrahedral geomatry
