الملخص العربي
The new four complexes of Co(II), Ni(II) ,Cu(II) and Zn(II), with a multidentate Schiff-base
ligand [H2L] derived from Bis[(2,4,-diformyl)-6- ethylenediamine phenol]and
Phenylenediamin were prepared.The complexes were synthesized in direct reaction of the
corresponding metal chloride with the ligand. The ligand and complexes have been
characterized by spectroscopic methods (IR,UV-Vis, 1HNMR,A.A),chloride content,melting
point and conductivity measurement.The data of these measurements suggest octahedral
geometry around Co(II) Ni(II) and Cu(II) ions and tetrahedral geometry around Zn (II) ion.
