Synthesis , Characterization and Biological Studies of Some New Mixed Nickel(II) Complexes Containing Dithiocarbamate and 1,10-phenanthroline Ligands

Complexes [Ni(dtc1)2(phen)] (I) , [Ni(dtc1)(phen)2]Cl (II) ,[Ni(dtc2)2(phen)] (III) ,[Ni(dtc2)(phen)2]Cl (IV) , [Ni(dtc1)(dtc2)(phen)] (V) and [Ni(dtc2)2(H2O)2], where dtc1=Benzyl dithiocarbamate , dtc2 = p-chloro benzyl dithiocarbamate ,phen=1,10-phenanthroline were prepared by reaction of NiCl2.6H2O with different mole ratio of phenanthroline and dithiocarbamate Ligands.All complexes were characterized by C H N analyses , IR ,UV-Vis. , 1H NMR and XRD diffraction . The analytical data indicated that the dithiocarbamate ligands and phen are coordinated as bidentate ligands.The biological activities of these compounds shows that some promising activity against gram positive bacteria (Staphylococcus aureus ) and gram negative bacteria (Aeromonas Keywords :Mixed ligand ,dithiocarbamate ,phenanthroline , benzyl amine ,nickel Complexes
