Abstract: The title compound, {[Cu₂(CN)(C₂H₈N₂)₄(H₂O)][Cu₂Zn₂(CN)₉]}_n, is a host-guest structure in which the host is constituted by the Zn^II and Cu^I atoms bridged by cyanide ions, and the guest consists of Cu^II, ethylenediamine, a cyanide and a water molecule. The guest and host species are linked through five N-HN hydrogen bonds. Zn^II and Cu^I in the host (or cation), have tetrahedral coordination. Cu^II in the guest (or anion) are penta- and hexacoordinated, leading to distorted square-pyramidal and square-bipyramidal structures, respectively
