Abstract: In the title compound, [Co(H2O)6](C14H10O6)·2H2O, the 2,2'-[naphthalene-1,8-diylbis(oxy)]diacetate dianion L is not coordinated to the CoII ion. The asymmetric unit contains half of the L dianion, half of a [Co(H2O)6]2+ cation (both molecules being completed by inversion symmetry), and one water molecule. The crystal packing features O-H...O hydrogen bonding between the carboxylate groups, the aqua ligands and the hydrate water molecules.
