Abstract

1, 3, 4-thiadiazole –benzenesulfonamide compounds are important due to these are have versatile pharmacological activity such as gonorrhea, scarlet fever, blood poisoning ,tonsillitis ,sinus infection ,urinary tract infection, antimicrobial , Antibacterial, Anti- thyroid, Anticancer ,Anti-tumor, Diuretic. anti-inflammatory .antiviral, antifungal, anti malarial, anti-HIV, Anticancer . In our present study Some Transition Metal Complexes which are Co(III), Fe(III), Cr(III), Cu(II), Ni(II) with New Ligand of N-(5-Sulfanyl-1,3,4-Thiadiazol-2-yl)Benzene Sulfonamide have been synthesized and identify by using the spectral methods of 1HNMR , Mass ,IR, as well as Molar conductance and C,H,N . It may be concluded for all the synthesized complexes ligand acts as a bidentate and coordinated through thiadiazole nitrogen and sulfonamide oxygen atoms. Its supported by the appearance of a band corresponding to the metal–nitrogen and the metal–Oxygen stretching vibration at 600–608 cm–1 and 485-488 cm–1 in the complexes. The physical and chemical data suggested the octahedral geometry for all complexes except for Cu and Ni complexes which where tetrahedral consequently .
