Synthesis, Characterization, And Antibacterial activity Of Mn (II),Fe(II),Co(II),Ni(II),Cu(II),Zn(II),Cd(II),and Hg (II) Mixed- Ligand Complexes Containing Furan-2-carboxylic acid And (1,10-phenanthroline)

摘要

The research includes the synthesis and identification of type mixed ligand complexes of M +2 Ions using Furan-2-carboxylic acid( C 5 H 4 O 3 ) (FCA H) as a primary ligand and 1,10-phenanthroline (phen )as secondary ligand.The resulting products were found to be solid crystalline complexes' which have been characterized by :Melting points, Solubility, Molar conductivity. determination the percentage of the metal in the complexes by flame(AAS), magnetic susceptibility, Spectroscopic Method [FT-IR and UV-Vis]. The proposed structure of the complexes using program , chem office 3D(2006) . The general formula have been given for the prepared mixed ligand complexes [M(FCA) 2 (phen) 2 ] M(II) - Mn (II) , Fe (II),Co(II) ,Ni(II),Cu (II), Zn(II) , Cd(II), and Hg (II). Phen = 1,10-phenanthroline = (C 14 H 8 N 2 .H 2 O) The results showed that the deprotonated ligand (Furan-2-carboxylic acid (FCA H) to (Furan-2-carboxylate ion (FCA - ) by using (KOH) coordinated to metal ions as a monodendate ligand through the oxygen atom of the carboxylate group (-COO - ),and the retention of ? (C-O-C) band of the (FCA - ) ring at 1224 cm -1 oxygen atom of the ring cm -1 indicates that is not taking part in coordination.
