Synthesis and Spectroscopic Identification Some Transitional Element Ions Complexes for 3d Series Derived new Mannich Base of Isatin.

Abstract

The present work includes preparation and spectral study of some transition metal complexes of Mn,Co,Ni,Cu(II)and Zn(II)with new Mannich base Z-1-(3-methoxy phenyl amines)methl-3-(p-tolyl)indolin-2-one that behaved as donating bi dentate Lewis base via nitrogen and oxygen atoms .The new Mannich base (L)was prepared in tow step , the first is condensation of indol -2,3-dion with 4-methylaniline ,and the second followed the reachion with formaldehyde and m-anisidine.All the complexes and the Ligand have identified on the basis of C.H.N.elemental analyses , flume atomic absorption ,NMR,IR,Uv- visible ,mass spectra. Furthermore the magnetic moment by Fardy method and molar conductivity measurement in DMF solvent revealed the tetrahedral geometry of [MLCl2].n H2O formal ,n= 1,2,for Co,Ni,Cu+2 .
