SYNTHESIS AND CHARACTERIZATION OF Mg(II), Fe(II) AND Co(II) METAL COMPLEXES OF 4-CHLORO-3-SULFAMOİLBENZOIC ACID DERİVATIVES

Abstract

Biological properties of sulfamoylbenzoic acid derivatives and metal complexes such as antimicrobial, antifungal, anti-inflammatory, antidiabetic, diuretic, meniscus, pain reliever, infection therapy, rheumatism therapy and enzyme inhibitor are found in the literature. In the literature, the structures of Na, K and Fe (III) complexes of 4-chloro-3-sulfamoylbenzoic acid (H34Cl3sba) have been explained by various spectroscopic methods. In this study, metal complexes of 4-chloro-3-sulfamoylbenzoic acid Mg (II) (Mg4Cl3sba), Fe (II) (Fe4Cl3sba) and Co (II) (Co4Cl3sba) were synthesized. The structures of transition metal complexes have been proposed by elemental analysis, AAS, IR, magnetic susceptibility, molar conductivity, charge balance and previous studies. The experimentally obtained elemental analysis and AAS results of the synthesized substances are in agreement with the amount of elements calculated from the structures proposed as a result of spectroscopic studies. Metal:ligand ratio of 1:2 was observed in all complexes. The stress and vibration bands that should be observed when examining the IR spectra of the complexes were observed in the spectra. In magnetic susceptibility studies of metal complexes, metal ions were found to be d0 in Mg4Cl3sba {Mg(II)}, d6 in Fe4Cl3sba {Fe(II)} and d7 in Co4Cl3sba {Co(II)}. As a result of conductivity measurements, it was observed that not all complexes were ionic. The structures of the synthesized metal complexes were linear for the Mg4Cl3sba complex and octahedral for the Fe4Cl3sba and Co4Cl3sba complexes.
