The γ-polymorph of AgZnPO(4) with an ABW zeolite-type framework topology

The γ-polymorph of the title compound, silver zinc orthophos­phate, was synthesized under hydro­thermal conditions. The structure consists of ZnO(4), PO(4) and AgO(4) units. The coord­ination spheres of Zn(II) and P(V) are tetra­hedral, whereas the Ag(I) atom is considerably distorted from a tetra­h...

description The γ-polymorph of the title compound, silver zinc orthophos­phate, was synthesized under hydro­thermal conditions. The structure consists of ZnO(4), PO(4) and AgO(4) units. The coord­ination spheres of Zn(II) and P(V) are tetra­hedral, whereas the Ag(I) 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 PO(4) and ZnO(4) 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-AgZnPO(4) is distinct from the two other polymorphs α-AgZnPO(4) and β-AgZnPO(4), but is isotypic with NaZnPO(4)-ABW, NaCoPO(4)-ABW and NH(4)CoPO(4)-ABW.
