Synthesis, Characterization, and Antibacterial Studies of Mn (II) , Fe (II) , Co(II) , Ni(II), Cu (II) and Cd(II) Mixed- Ligand Complexes Containing Amino Acid ( L-Valine) And (1,10- phenanthroline)

Abstract

A new six mixed Ligand complexes of some transition metal ions Mn (II) , Fe (II) , Co(II) , Ni(II), Cu(II)and non transition metal ion Cd(II)) with L-valine (Val H ) as a primary Ligand and 1,10-phenanthroline(phen) as a secondary Ligands have been prepared. All the prepared complexes have been characterized bymolar conductance, magnetic susceptibility infrared ,electronic spectral and AAA . The complexes with theformulas [M(Val)2(phen)] , M= Mn (II) , Fe (II) , Co(II) , Ni(II), Cu (II) ,and Cd(II) , L- Val H=(C5H11NO2) ,(C12H8N2) =(phen)Key words: Amino Acid,( L-valine), 1,10-Phenanthroline, mixed ligand complexes, Antibacterial activities,spectral studies
