SYNTHESIS AND CHARACTERIZATION OF MIXED-LIGAND Cu(II) COMPLEXES OF 2,4-DICHLORO-5-SULFAMOYLBENZOIC ACID AND 2-AMINOPYRIDINE DERIVATIVES

Abstract

The usage areas of 2,4-dichloro-5-sulfamoylbenzoic acid and its derivatives such as antidiabetic, anti-inflammatory, antimicrobial, antifungal, rheumatism therapy, pain reliever, enzyme inhibitor, diuretic and meniscus are found in the literature. In the literature, Fe (III) complex, ethylenediamine, 2 amino-3-methylpyridine and 2-aminomethylpyridine with salt and 2 aminomethylpyridine {Zn (II)}, 4,4'-bipyridine {Co(II), Cu(II), Zn(II) and Cd(II)} and 1,3-bis (4-pyridyl) propane {Cd(II), Ag(I) and Pb (II)} mixed ligand metal complexes of 2,4-chloro-5-sulfamoylbenzoic acid (Hsba) synthesized and structures were investigated.In this study, with 2,4-chloro-5-sulfamoylbenzoic acid and 2-aminopyridine derivatives (2-amino-3-hydroxypyridine (2a3OHp), 2-amino-3-bromo-5-nitropyridine (2a3Br5NO2p) and 2-amino-3,5-dibromopyridine (2a35DBrp)) mixed ligand Cu (II) metal complexes (Cusba2a3OHp, Cusba2a3Br5NO2p and Cusba2a35DBrp) were synthesized. The structures of Cu(II) complexes have been proposed by elemental analysis, AAS, IR, molar conductivity, magnetic susceptibility. The theoretically obtained values of the synthesized substances and the elemental analysis and AAS values obtained experimentally are in accordance with the structures proposed as a result of spectroscopic studies. The metal: acid: base ratio of 1:2:2 was observed in all the complexes. There are stress and vibration bands that are expected to be observed in the IR spectra of the complexes. In sensitivity studies of the complexes, it was observed that d9 {Cu(II)} in all complexes. In conductivity measurements, it was observed that the complexes were not ionic. It has been observed that all of the synthesized metal complexes are octahedral
