In the title compound, [Cu(ClO4)2(C12H8N2)(H2O)2], the CuII atom is coordinated in a square-planar fashion by the two N atoms of a chelating 1,10-phenanthroline ligand and by two water molecules trans to the N atoms. The coordination sphere of the metal atom is augmented by O atoms of two weakly bonded perchlorate anions, thus yielding a strongly distorted CuN2O4 octahedral environment. The crystal packing is stabilized by O-HO hydrogen bonds between the water molecules and the perchlorate anions. In addition, the organic molecules are associated by - stacking interactions between symmetry-equivalent antiparallel non-nitrogen aromatic rings, with interplanar distances of 3.543 (2) Å.
