Hexaaqua-cobalt(II) bis-(5-acetyl-2-hy-droxy-benzoate) dihydrate.

In the title compound, Co(H(2)O)(6)(2)·2H(2)O, the Co(2+) cation lies on a twofold rotation axis and is coordinated by six water mol-ecules in a distorted octa-hedral geometry. In the 5-acetyl-2-hy-droxy-benzoate anion, the hy-droxy group links with the carboxyl-ate group via an intra-molecular O-H⋯O hydrogen bond and the acetyl group is twisted to the benzene ring at a dihedral angle of 16.99 (12)°. In the crystal structure, the cations, anions and water mol-ecules are linked by extensive O-H⋯O hydrogen bonding.
