Hexaaquacobalt(II) 2,2′-[naphthalene-1,8-diylbis(oxy)]diacetate dihydrate

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.
