Abstract: The title compound, [Co(C₄H₇N₂O₂)₂(C₂H₉N₂)₂][Co(C₄H₆N₂O₂)Cl₂(C₄H₈N₂O₂)]Cl₂·0.75H₂O, contains a Co-centered cation and a Co-centered anion, together with two uncoordinated Cl^- anions and a total of 0.75 uncoordinated water molecules in the asymmetric unit. Both Co atoms are six-coordinated in distorted octahedral configurations, with two dimethylglyoximate and two protonated ethylenediamine ligands attached to the Co atom in the cation; a dimethylglyoximate and a dimethylglyoxime ligand with two Cl^- anions are bonded to the Co atom in the anion. The Co atom belonging to the cation lies on a inversion center, while the anion centered on the other Co atom lies on a mirror plane, as does one of the disordered water molecules.
