RESUMO
In the title compound, [Co(H(2)O)(6)](C(9)H(7)O(4))(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-Hâ¯O hydrogen bond and the acetyl group is twisted to the benzene ring at a dihedral angle of 16.99â (12)°. In the crystal structure, the cations, anions and water mol-ecules are linked by extensive O-Hâ¯O hydrogen bonding.
