Summary

<strong>ABSTRACT</strong><br /> Aseries of new complexes of the type [MLCl₂] where M=Mn (II),Co(II),Ni(II),Cu(II),Zn(II),Cd(II) L=L¹ or L² represents di- Schiff base ligands: {L¹=(N,N'E,N,N'E)-N,N'-(phenanthrene-9,10-diylidene) bis (benzene-1,2-diamine). L²=(N,N'E,N,N'E)-N,N'-(phenanthrene-9,10-di ylidene)bis(benzene-1,3-diamine)} have been prepared in (1:1)(M:L) molar ratio and charactrerized by electrical conductivity,magnetic moment, IR , UV-VIS and metal content analysis.<br /> Conductivity data in DMF and DMSO solution showed that all complexes are non-electrolytes. Magnetic moment and electronic spectra indicate that some of the complexes have a tetrahedral geometry  and the others have an square planar environment . The antibacterial activity against <em>E.coli</em> and <em>S.aureus</em> of L¹ and L² and some of their complexes derived from Cu(II) and Zn(II) illustrates that the complexes have higher activity than the corresponding organic ligand.
