Complexes of Mn(II), Fe(III), Co(II), Ni(II), Cu(II) and Zn(II) with Schiff bases derived from isatin and ethylenediamine (L1) or diethylenetriamine (L2) have been synthesized and characterized by microanalysis, IR, UV-Vis, 1H NMR, EPR and conductance measurements. Electrical conductance of the Fe(III) chelates indicated them to be 1:1 electrolyte whilst those of divalent metal ions are non-electrolytes in DMSO. On the basis of magnetic moment and spectral data a pseudooctahedral geometry has been suggested for all of the complexes. The EPR spectrum of [Cu(L1)Cl2] complex indicates a considerable exchange interaction in the solid state.
