title: Diaqua-(2,2'-bipyridine-κN,N')bis-(perchlorato-κO)copper(II).
abstract: 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.
