Abstract: In the title compound, {[Cu(C₆H₅N₂O₂)₂]·2H₂O}_n, the Cu^II ion (site symmetry ) is coordinated by two N,O-bidentate ligands and two N-monodentate ligands in a distorted CuO₂N₄ octahedral geometry. Each anion acts as a bridge between two cations, thus forming a two-dimensional polymeric network parallel to the ab plane. The packing is consolidated by O-HO hydrogen bonds. One of the O atoms of the ligand and both water molecules are disordered.
