The central CuN₂O₄ motif of the title compound, [Cu(ClO₄)₂(C₁₀H₈N₂)(H₂O)₂], exhibits a Jahn-Teller-distorted octahedral geometry around the metal atom, showing a considerably long Cu-O bond distance of 2.5058 (12) Å towards the second perchlorate group, giving a (4 + 1+1)-type coordination mode. In the crystal, the components are linked via intermolecular O-HO hydrogen bonds, forming layers parallel to (001). Additional stabilization within these layers is provided by [pi] - [pi] [centroid-centroid distances of 3.7848 (9)-4.4231 (9) Å] stacking interactions.
