In the centrosymmetric binuclear cation of the title compound, [Cu(C8H7O4)(H2O)(C5H5N)2]2(ClO4)2, the CuII atoms are bridged by a pair of two dehydroacetate anions in a bis-/monodentate mode. The distorted octahedral N2O4 coordination sphere of the metal cation is completed by two pyridine N atoms and one O atom of a water molecule. The complex cations and the perchlorate counter anions are arranged in layers parallel to (100). O-H...O hydrogen bonds between the coordinating water molecules and the perchlorate anions constitute ribbons parallel to [10-1]. C-H...O hydrogen bonds are also observed.
