Bis[(4-chlorophenoxy)acetato-κO](ethylenediamine-κ2 N,N′)zinc

Abstract

The mononuclear title complex, [Zn(C8H6ClO3)2(C2H8N2)], was obtained by the reaction of zinc(II) acetate dihydrate with p-chlorophenoxyacetic acid (pCPA) and ethylenediamine (EDA) in a water/ethanol mixture. The ZnII cation has a distorted tetrahedral coordination sphere involving two carboxylate O atoms of two monodentate pCPA ligands and two N atoms of one chelating EDA ligand. The pCPA ligands coordinate asymmetrically to the ZnII cation with two different Zn—O distances of 1.967 (3) and 1.978 (3) Å. In the crystal, molecules are linked by N—H...O hydrogen bonds, forming chains propagating parallel to [100]. These chains are linked by C—H...O hydrogen bonds, C—H...π stacking and Cl...Cl interactions, generating a three-dimensional supramolecular network.
