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

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