Complexes of some metal ions ( Mn(I? ) , Co(??) , Ni(??) ,Cu (??) , Zn(I?) , Cd (??) , and Hg(??) ) with 8-hydroxyquinoline (Oxine) and 2- Picoline (2-pic ) have been synthesized and characterized on the basis of their FT-IR. and Uv-visible spectroscopy ,atomic absorption molar conductivity measurements and magnetic susceptibility ,from the results obtained the following general formula has been given for prepared complexes [M (oxine)2 (2-pic)2]where M = M(??) = Mn , Co , Ni , Cu , Zn , Cd , Hg(oxine)- = ionic ligand 8-hydroxyquinolin (oxinato)(2- pic) = 2- picolin

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)

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.

Synthesis, spectral and antimicrobial activity of mixed ligand complexes of Co(II), Ni(II), Cu(II) and Zn(II) with Anthranillic Acid and Tributylphosphine

Mixed ligand complexes of bivalent metal ions, viz; Co(II), Ni(II), Cu(II) and Zn(II) of the composition [M(A)2((PBu3)2]in(1:2:2)(M:A:(PBu3).  molar ratio, (where A- Anthranilate ion ,(PBu3)= tributylphosphine. M= Co(II),Ni(II),Cu(II) and Zn(II). The prepared complexes were characterized using flame atomic absorption, by FT-IR, UV/visible spectra methods as well as magnetic susceptibility and conductivity measurements. The metal complexes were tested in vitro against three types of pathogenic bacteria microorganisms: (Staphylococcus, Klebsiella SPP .and Bacillas)to assess their antimicrobial properties. Results. The study shows that all complexes have octahedral geometry; in addition, it has high activity against tested bacteria. Based on the reported results, it may be concluded that.The results showed that the deprotonated ligand(nthranilc acid ) to anthranilate ion (A-) by using (KOH) 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 Tributylphosphine coordinated as a monodentate through the  phosphor atom.   Keywords :Mixed(anthranilic acid or tributylphosphine) complexes, spectroscopy studies, mixed ligands  and  Antibacterial Activitie
