Nickel(II), cobalt(II) and copper(II) complexes of H 2 L and H 2 L Á NaCl have a metal-ligand ratio of 1:2 and the ligand coordinates through the two N atoms, as do most of the vic-dioximes. * Correspondence: Emin Karapınar, Department of Chemistry, Faculty of Arts and Sciences, Pamukkale University, 20017 Denizli, Turkey; E-mail: eminkarapinar@ hotmail.com. 1319 DOI: 10.1081/SIM-120024312 0094-5714 (Print); 1532-2440 (Online) Copyright D 2003 by Marcel Dekker, Inc. www.dekker.com
