title: Diaqua-bis(5-carb-oxy-1H-pyrazole-3-carboxyl-ato-κN,O)cobalt(II) dihydrate.
abstract: In the title complex, [Co(C(5)H(3)N(2)O(4))(2)(H(2)O)(2)]·2H(2)O, the Co(II) ion lies on an inversion center and is coordinated in a distorted octa-hedral environment. In the crystal structure, complex and water mol-ecules are linked into a three-dimensional network by O-H⋯O and N-H⋯O hydrogen bonds.
