Zinc(II) and cobalt(II) complexes of (3-carboxymethoxy-naphthalen-2-yloxy)-acetic acid: a structural study

Author affiliations


Different types of cyclic polynuclear complexes and one-dimensional coordination polymers of zinc(II) derived from (3-carboxymethoxy-naphthalen-2-yloxy)-acetic acid (LH2) are synthesised and characterised. The macrocyclic effect of ligand L leads to the formation of a coordination polymer having composition {[Na2Zn2(L)2(OH)2]}n and a binuclear zinc complex having composition [Zn2Na2(L)2(CH3COO)2(Pyz)2(MeOH)2] (where Pyz = pyrazole). A tetranuclear cyclic zinc(II) metallacycle with two dimethylformamide molecules in two different environments is synthesized and it has two symmetry non-equivalent cyclic molecules in its unit cell. The mononuclear complexes of zinc with L and the bidentate ligands such as 2,2′-bipyridine or 1,10-phenanthroline ancillary ligands are structurally characterised.
