Abstract

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—H⋯O hydrogen bonds, forming layers parallel to (001). Additional stabilization within these layers is provided by π–π [centroid–centroid distances of 3.7848 (9)–4.4231 (9) Å] stacking inter­actions.
