Synthesis, Characterization, And Antibacterial Activities Of Manganese (II), Cobalt(II), Iron (II), Nickel (II) , zinc (II) And Cadmium(II) Mixed- Ligand Complexes Containing Amino Acid(L-Valine) And Saccharin
Abstract
A new six mixed ligand complexes of some transition metal ions Manganese (II), Cobalt(II), Iron (II), Nickel (II) , and non transition metal ion zinc (II) And Cadmium(II) with L-valine (Val H ) as a primary ligand and Saccharin (HSac) as a secondary ligands have been prepared. All the prepared complexes have been characterized by molar conductance, magnetic susceptibility infrared, electronic spectral, Elemental microanalysis (C.H.N) and AA . The complexes with the formulas [M(Val)2(HSac)2]
M= Mn (II) , Fe (II) , Co(II) ,Ni(II), Cu (II),Zn(II) and Cd(II)
L- Val H= (C5H11NO2) , C7H5NO3S
The study shows that these complexes have octahedral geometry; The metal complexes have been screened for their in microbiological activities against bacteria. Based on the reported results, it may be concluded that the deprotonated ligand (L-valine) to (valinate ion (Val-) by using (Na OH) coordinated to metal ions as bidentate ligand through the oxygen atom of the carboxylate group(-COO-), and the nitrogen atom of the amine group (NH2), where the saccharin (H Sac) coordinated as a monodentate through the nitrogen atom.
Keywords: L-Valine , mixed ligand complexes, Saccharin , spectral studies , Antibacterial activities.
