[H3N(CH2)(3)NH3](0.5)ZnPO4, a new member of the zeolite gismondine family

The solution-mediated synthesis and single crystal structure of [H3N(CH2)(3 )NH3](0.5)ZnPO4 are reported. This phase is built up from vertex-linked ZnO 4 and PO4 building units encapsulating the extra-framework I,3-diammonium p ropane molecules. The 4/8-ring framework topology corresponds to that of th e zeolite gismondine family. Crystal data: [H3N(CH2)(3)NH3](0.5)ZnPO4.
