Abstract

In the title compound, [Co(C8H5Cl2O3)(C12H12N2)], the CoII atom, lying on a twofold rotation axis, is coordinated by four O atoms from two chelating 2,4-dichlorophenoxyacetate ligands and two N atoms from a 5,5′-dimethyl-2,2′-bipyridine ligand, displaying a distorted octahedral geometry. A three-dimensional supramolecular structure is formed through intermolecular C—H⋯O hydrogen bonds and π–π stacking interactions between the pyridine and benzene rings [centroid–centroid distance = 3.779 (2) Å].

Highlights

In the title compound, [Co(C8H5Cl2O3)(C12H12N2)], the CoII atom, lying on a twofold rotation axis, is coordinated by four O atoms from two chelating 2,4-dichlorophenoxyacetate ligands and two N atoms from a 5,50 -dimethyl-2,20 -bipyridine ligand, displaying a distorted octahedral geometry
