Synthesis and Characterization of Complexes of Isatin Schiff Base

Rafat F., Siddigi K. S., Siddiqi M. Y.

Polish Journal of Chemistry

2005

Vol. 79 / nr 4

663-670

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.
