Abstract: The asymmetric unit of the title complex, [Cu(C₂H₈N₂)₂(H₂O)₂](C₈H₈NO₂)₂·2H₂O, contains one anion, one half-cation and one water molecule. The Cu^II atom in the [Cu(en)₂(H₂O)₂]²⁺ cation (en is ethylenediamine) lies on an inversion centre. The four N atoms of the en ligands in the equatorial plane around the Cu^II atom form a slightly distorted square-planar arrangement, while the slightly distorted Jahn-Teller octahedral coordination is completed by two water O atoms in axial positions. In the crystal structure, intra- and intermolecular N-HO and O-HO hydrogen bonds form a three-dimensional network.
