Abstract
In this work, 5-bromoanthranilic acid was condensed with 1-(5-benzoyl-1H-1,2,3-benzotriazole-1-yl)-2-chloro-ethanone to form 2-{[2-
(5-benzoyl-1H-benzotriazol-1-yl)-2-oxoethyl]amino}-5-bromobenzoic acid. The newly synthesized ligand and its metal(II) complexes
with first transition metal series (Cu(II), Ni(II), Co(II), Zn(II) and Mn(II)) have been synthesized and characterized by using elemental
analysis, infrared and electronic spectra. The IR spectra, NMR spectra and atomic absorption analysis show that the benzotriazole ligand
formed chelates with metal in a 2:1 (ligand:metal) stochiometry. All the metal(II) complexes were screened for their antibacterial activity
against Gram-positive and Gram-negative bacteria. Among the synthesized metal(II) complexes, Cu(II) complex showed the highest
antibacterial activity.
