In the title compound, [Cu(C5H4ClNO)2(C4H4N2)(H2O)2](ClO4)2, the Cu atom, which lies on an inversion centre, has an octahedral environment. The pyrazine ligand also lies about an inversion centre and links adjacent Cu atoms into a chain running along the b axis; perchlorate anions occupy the space between the chains, and the chains use the coordinated water mol­ecules to link to the anions, resulting in a hydrogen‐bonded ribbon structure. The donor 5‐chloro‐2‐hydroxy­pyridine ligand exists in the zwitterionic form, i.e. 5‐chloro­pyridinium‐2‐olate.
