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)

Abstract

The research includes the synthesis and identification of type mixed ligand complexes of

M⁺² Ions using Furan-2-carboxylic acid( C₅H₄O₃) (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 = (C₁₄H₈N₂.H₂O)    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.
