Diaquabis(5-carboxy-1H-pyrazole-3-carboxylato-κ2N2,O3)cobalt(II) dihydrate

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.
