Metal Complexes Of Schiff Bases: Preparation, Characterization, And Biological Activity, Gehad Genidy Mohamed, Mohamed Mohamed Omar, Ahmed Mohamed Hindy
Turkish Journal of Chemistry
Metal complexes of Schiff bases derived from 2-furancarboxaldehyde and o-phenylenediamine (L^1), and 2-thiophenecarboxaldehyde and 2-aminothiophenol (HL^2) are reported and characterized based on elemental analyses, IR ^1H NMR, solid reflectance, magnetic moment, molar conductance, and thermal analysis (TGA). The ligand dissociation, as well as the metal-ligand stability constants were calculated, pH-metrically, at 25 °C and ionic strength \mu = 0.1 (1 M NaCl). The complexes are found to have the formulae [M(L^1)(H_2O)_2](Cl)_n \cdot yH_2O (where M = Fe(III), Ni(II), Cu(II); n = 2-3, y = 2-4); [M(L^1)](X)_2 \cdot yH_2O (where M = Co(II), Zn(II), UO_2(II), X = Cl, AcO or NO_3, …

Synthesis Of Vic-Dioxime Derivatives With Hydrazone Side Groups And Their Metal Complexes, İlknur Babahan, Hüseyi̇n Anil, Nursabah Sarikavakli
Turkish Journal of Chemistry
Two novel vic-dioxime (L^1H_2, L^2H_2) compounds bearing hydrazone side groups and their transition metal complexes Ni(II), Co(II), Cu(II), and Zn(II) were synthesized. The vic-dioxime ligands bearing hydrazone side groups were synthesized by reacting anti-glyoximehydrazine (GH_2) with 4-nitroacetophenone and 4-methylacetophenenone, respectively. Ligands form mononuclear complexes [(LH)_2M] with a metal to ligand ratio of 1:2 with M=Co(II)(H_2O)_2, Ni(II), and Cu(II). Zn(II) forms complexes [(LH)(H_2O)(Cl)Zn] with a metal to ligand ratio of 1:1. The Co(II) complexes of the ligands are proposed to be octahedral with water molecules as axial ligands, the Ni(II) and Cu(II) complexes are proposed to be square planar, and the …

The Synthesis Of 4-Phenoxyphenylglyoxime And 4,4'-Oxybis(Phenylglyoxime) And Their Complexes With Cu(Ii), Ni(Ii) And Co(Ii), Ahmet Coşkun
Turkish Journal of Chemistry
4-Acetyldiphenyl ether and 4,4'-diacetyldiphenyl ether were synthesized from diphenyl ether and acetyl chloride in the presence of AlCl_3 used as catalyst. Subsequently, their keto oxime and glyoxime derivatives were prepared. The metal complexes of the glyoximes such as Cu(II), Ni(II) and Co(II) were also prepared. The structures of these ligands and their complexes were identified by FT-IR, ^1H NMR and ^{13}C NMR spectral data, elemental analysis and magnetic measurements.
