Bis[μ-(3-acetyl-2-hy­droxy-6-methyl-4H-pyran-4-one-κ(3) O:O′,O′′)]diaqua­tetra­kis­(pyridine-κN)dicopper(II) diperchlorate

In the centrosymmetric binuclear cation of the title compound, [Cu(C(8)H(7)O(4))(H(2)O)(C(5)H(5)N)(2)](2)(ClO(4))(2), the Cu(II) atoms are bridged by a pair of two dehydro­acetate anions in a bis-/monodentate mode. The distorted octa­hedral N(2)O(4) 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.
