✦ Synopsis

The Co II atom in the mononuclear title complex, [Co(C 8 H 5 -Cl 2 O 3 ) 2 (C 3 H 4 N 2 ) 2 (H 2 O) 2 ], lies on an inversion center. The Co II atom has an octahedral coordination, involving two carboxylate O atoms of two monodentate 2,4-dichlorophenoxyacetate ligands, two N atoms of imidazole ligands and two water molecules. Intermolecular O-HÁ Á ÁO hydrogen bonds give rise to chains, which are linked by N-HÁ Á ÁO hydrogen bonds, forming a sheet structure. The molecules are further linked bystacking interactions, generating a twodimensional supramolecular network.
