Abstract

Novel transition metal [Cu(II), Ni(II), Zn(II), La(II)] complexes of bidentate Schiff base ligand obtained from 2-hydroxy-3-formylquinoline and substituted p-iodoaniline have been prepared and characterized by physical, spectral and analytical data. The synthesized Schiff base act as bidentate ligand for the complexation reaction with Cu(II), Ni(II), Zn(II) and La(II) ions. The new compounds, possessing the general formula [M(L)2] where [M= Cu(II), Ni(II), Zn(II) and La(II)] show square planar geometry.
