The γ-polymorph of the title compound, silver zinc orthophosphate, was synthesized under hydrothermal conditions. The structure consists of ZnO4, PO4 and AgO4 units. The coordination spheres of ZnII and PV are tetrahedral, whereas the AgI atom is considerably distorted from a tetrahedral coordination. Each O atom is linked to each of the three cations. An elliptic eight-membered ring system is formed by corner-sharing of alternating PO4 and ZnO4 tetrahedra, leading to a framework with an ABW-type zeolite structure. The framework encloses channels running parallel to [100] in which the Ag cations are located, with Ag⋯Ag contacts of 3.099 (3) Å. This short distance results from d 10⋯d 10 interactions, which play a substantial role in the crystal packing. The structure of γ-AgZnPO4 is distinct from the two other polymorphs α-AgZnPO4 and β-AgZnPO4, but is isotypic with NaZnPO4-ABW, NaCoPO4-ABW and NH4CoPO4-ABW.
