[H3N(CH2)3NH3]0.5[ZnPO4], an organically templated zincophosphate analogue of the aluminosilicate zeolite edingtonite

Hydro­thermally prepared propane-1,3-di­ammonium bis­(zinc phosphate), [H3N(CH2)3NH3]0.5[ZnPO4] is an analogue of the aluminosilicate zeolite edingtonite. A three-dimensional network of vertex-sharing ZnO4 and PO4 tetrahedra [dav(Zn—O) = 1.945 (9) Å, dav(P—O) = 1.513 (10) Å and θav(Zn—O—P) = 134 (5)°] encapsulate the highly disordered propane-1,3-di­ammonium cations in a three-dimensional 8-ring channel system.
