The title complex, [Co(H2O)6][Co2(TTHA)(H2O)2]·4H2O (TTHAH6 = triethylenetetraminehexaacetic acid), consists of discrete [Co(H2O)6]2+ cations and [Co2(TTHA)(H2O)2]2− binuclear anionic units. Each Co(II) ion in the binuclear units is coordinated by one water and half a TTHA6− anion as a pentadentate ligand, giving a distorted octahedral arrangement. The [Co(H2O)6]2+ cation lies on a center of inversion in the crystal and exhibits strong hydrogen-bond interactions with four carboxylate groups from the TTHA6− ligand and the water molecules, leading to the formation of a three-dimensional network.
