Synthesis, characterization, crystal structure, and biological studies of a cadmium(II) complex with a tridentate ligand 4′-chloro-2,2′: 6′,2″-terpyridine

Abstract

A new Cd(II) complex with the ligand 4′-chloro-2,2′6′, 2″-terpyridine (Cltpy), [Cd(Cltpy)(I)2], has been synthesized and characterized by CHN elemental analysis, 1H-NMR, 13C-NMR, and IR spectroscopy and structurally analyzed by X-ray single-crystal diffraction. The single-crystal X-ray analyses show that the coordination number in complex is five with three terpyridine (Cltpy) N-donor atoms and two iodine atoms. The antibacterial activities of Cltpy and its Cd(II) complex are tested against different bacteria. © 2011 L. A. Saghatforoush et al.
