Synthesis and characterization of the new Tetradentate Schiff base ligand type N4 derived From 4-animoantipyrine,4-dimethylaminobenzaldehyde, ethylenediamine and furfural, towards Fe(III), Co(II), Cu(II), Zn(II) and Hg(II) Ions

Abstract

Iron(III), Cobalt(II), Cupper(II), Zinc(II) and Mercury(II) complexes have been synthesized by reaction of their chloride salt with a new tetradentate Schiff base ligand type N₄: (N¹Z,N²Z)-N¹-(4-((Z)-4-(dimethylamino)benzylideneamino)-2,3-dimethyl-1-phenyl 1,2dihydropyrazol-5-ylidene)-N²(4((Z)-furan-2-ylmethyleneamino)-2,3-dimethyl-1-phenyl-1,2dihydropyrazol-5-ylidene)ethane1,2–diamine. All the prepared complexes were characterized by the spectroscopic methods (FT.IR, UV-Vis) Atomic Absorption, Magnetic Susceptibility, Melting Point, Elemental Analysis and Molar Conductivity, as well as the H1NMR for the free ligand. According to the resulted data from the above mentioned techniques, the octahedral structure geometry was proposed for Fe(III) complex with the formula [FeLCl₂]Cl, and tetrahedral geometry was proposed for the rest with a general formula [ML]Cl₂.
