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 .
