The central CuN(2)O(4) motif of the title compound, [Cu(ClO(4))(2)(C(10)H(8)N(2))(H(2)O)(2)], exhibits a Jahn-Teller-distorted octa-hedral 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 inter-molecular 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 inter-actions.
标题化合物[Cu(ClO₄)₂(C₁₀H₈N₂)(H₂O)₂]的中心CuN₂O₄ motif在金属原子周围呈现出 Jahn-Teller 畸变的八面体几何构型，朝向第二个高氯酸根基团显示出相当长的 Cu - O 键距，为 2.5058 (12) Å，呈现出(4 + 1 + 1)型配位模式。在晶体中，各组分通过分子间 O - H⋯O 氢键相连，形成平行于(001)的层。这些层内通过 π - π [质心 - 质心距离为 3.7848 (9) - 4.4231 (9) Å]堆积相互作用提供额外的稳定性。
