dc.description.abstractCobalt, nickel and zinc N-heterocycle chelated ethylenediaminediacetates [Co(edda)(Phen)]center dot(NH(4)Cl)center dot 1/3H(2)O (1), [Ni(edda)(phen)]center dot 3H(2)O (2). [Co(edda)(bpy)]center dot(NH(4)Cl)center dot 2H(2)O (3), [Ni(edda)(bpy)]center dot 4H(2)O (4), [Zn(edda)(bpy)]center dot 4H(2)O (5) (H(2)edda = ethylenediaminediacetic acid, phen = 1,10-phenanthroline, bpy = 2,2'-bipyridine) were isolated in pure forms and characterized spectroscopically. The X-ray structural analyses reveal that neutral mononuclear complexes contain both edda and phen/bpy ligands. Divalent metal ions are octahedrally bound by a bidentate phen or bpy ligand, and a tetradentately edda through carboxyl and amine groups. The co-existences of phen/bpy and edda in the complexes show no decomposition between phen/bpy and edda ligands. This is supported by the trace of (13)C NMR spectra with less-bound zinc complex. Further comparisons of the bond distances between Co(2+)//Ni(2+)/Zn(2+) ions with edda indicate that cobalt and nickel interact much stronger than those of zinc complexes. (C) 2011 Elsevier B.V.
