Abstract: In the binuclear title complex, [Cu2(ClO4)1.5(NO3)1.5(C18H16N6Se)(H2O)5]NO3·H2O, both CuII ions are hexacoordinated by O and N atoms, thus forming axially elongated CuO4N2 octahedra. The equatorial plane of each octahedron is formed by one chelating pyrazole-pyridine fragment of the organic ligand and two water molecules. The axial positions in one octahedron are occupied by a water molecule and a monodentately coordinated perchlorate anion, while those in the other are occupied by a nitrate anion and a disordered perchlorate/nitrate anion with equal site occupancy. The pyrazole-pyridine units of the organic selenide are trans-oriented to each other with a C-Se-C angle of 96.01 (14)°. In the crystal, uncoordinated nitrate anions and the coordinating water molecules are involved in O-HO and N-HO hydrogen bonds, forming a bridge between the pyrazole group and the coordinating water molecules. Further O-HO hydrogen bonds between the complex molecules and a - stacking interaction with a centroid-centroid distance of 3.834 (4) Å are also observed.
