In the title compound, [Cu(ClO4)2(C2H8N2)(C5H5N)2], the CuII cation is located on a twofold rotation axis and is coordinated by four N and two O atoms in a tetragonally distorted octahedral geometry. The crystal packing can be described as ClO4 tetrahedra and CuN4O2 octahedra alternating in a zigzag fashion along the c axis. The structure is stabilized by intermolecular N—H
O and C—HO hydrogen bonds, as well as π–π interactions [centroid–centroid distance = 3.7179 (15) Å].

In the title compound, C15H17NO3, the mean planes of the pyrrole and benzene rings form a dihedral angle of 81.92 (7)°. The molecule contains an intramolecular O—HO hydrogen bond. In the crystal, weak C—Hπ interactions link the molecules into chains along [010].

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—HO hydrogen bonds between the coordinating water molecules and the perchlorate anions constitute ribbons parallel to [10-1]. C—HO hydrogen bonds are also observed.
