Ligating Behavior Of Some Sulphur Containing Benzotriazole Derivatives Towards Some Transition Metal Ions And Their Biological Effect

Abstract: New Cu 2+ and Ni 2+ complexes of N 1 -phenyl-2-[1H-1,2,3-bezotriazol-1-yl] 3-phenyl-3-oxopropane thioamide, HL, has been synthesized and characterized by different spectral and magnetic measurements and elemental analysis. The spectral studies indicated that HL exist in the thion form in the solid state and the IR spectra of the complexes indicated that the ligand act as monobasic bidentate ligand giving distorted tetragonal structure in case of Cu 2+ and square planar structure in case of Ni 2+ , which was the reason of their different antimicrobial activity. Thermal decomposition of both complexes showed similar steps
