【 摘 要 】

In the title compound, [Cu(C4H3N2O2)2(H2O)2]·2H2O, the CuII ion is located on an inversion centre and exhibits an axially elongated octa­hedral coordination geometry. The equatorial plane is formed by two N,O-bidentate 1H-pyrazole-3-carboxyl­ate ligands in a trans configuration. The axial positions are occupied by two water mol­ecules. The mononuclear complex mol­ecules are arranged in layers parallel to the ab plane. Each complex mol­ecule is linked to four adjacent species through inter­molecular O—H⋯O and N—H⋯O hydrogen bonds that are established between the coordinating water mol­ecules and carboxyl­ate O atoms or protonated N atoms of the organic ligands. These layers are further connected into a three-dimensional network by additional hydrogen bonds involving solvent water mol­ecules and non-coordinating carboxyl­ate O atoms.
