Abstract
bis(2-(2′hydroxy-5′-methylphenyl)-benzotriazole) zinc was prepared by meams of methanol-water precipitation using 2-(2′-hydroxy-5′-methylphenyl)benzotriazole(HMPB) as ligand.The compound was characterized and analyzed by means of several testing techniques such as elemental analysis,infrared spectrum,UV-Vis spectra,mass spectrum etc..The results show that the ligand coordinates with the center metal ion by nitrogen and oxygen atoms in the form of bidentate ligand.The complex has strong absorption in a near ultraviolet region.The maximum absorption peak located at 340 nm.
