In the title salt, [Co(C(5)H(4)N(2)O(2))(2)(H(2)O)(2)]Cl(2), the Co(II) ion is located on an inversion center. It is chelated by two neutral pyrimidine-2-carboxylic acid molecules and is coordinated by two water mol-ecules in an octa-hedral coordination geometry. The cations and anions are linked via O-H⋯Cl hydrogen bonds into a layer structure; an intra-molecular O-H⋯N hydrogen bond connects the carboxylic acid group to the pyrimidine N atom.
