خلاصه مقاله:
۴-Amino-N-(۵-methyl-isaxazol-۳-yl)-benzenesulfonamide, a new azo (LH) ligand, was synthesized by reacting the diazonium salt of Sulfamethoxazole with coupling compound ۳-amino phenol. Spectroscopic techniques (UV-Vis, FTIR, ۱H &۱۳C-NMR, and LC-Mass) as well as micro elemental analyses (C.H.N.O) and TGA and SDC were used to identify the azo ligand. Complexes of (Zn(II), Cr(III), Cu(II) and VO(II)) were produced and characterized by atomic absorption, elemental microanalysis, infrared, LC-Mass, TGA, DSC and UV-Vis spectral techniques, as well as conductivity and magnetic quantifications. All the complexes had a ۱:۲ metal-ligand ratio, and non-electrolytes at all complexes and tetrahedral geometry suggested except Cr-complex, which demonstrated octahedral and VO-complex that demonstrated Square pyramidal. The results of the thermal decomposition indicated the presence of coordinated water molecule for only Cr-complex. The biological activity of some prepared compounds against two types of bacteria and four types of fungi was also studied, suggesting varying inhibition values.
