The results of single-crystal X-ray structure analysis have shown that both complexes form one-dimensional chains in which the dppeO2 functions as a bidentate O,O'-donor ligand bridging the cobalt(II) central atoms. The Co(II) atoms are hence tetracoordinated by two oxygen atoms from two distinct molecules of dppeO2 and two halogenido ligands yielding a distorted tetrahedral chromophore of {CoO2X2}. Spectral properties of both complexes were studied by IR and UV–Vis spectroscopy.
