Abstract

The synthesis and structure Of (CH3CH[NH3]CH2NH3)(1/2) . ZnPO4, an organically templated zincophosphate (ZnPO) analogue of aluminosilicate zeolite thomsonite (THO), are described. The ZnPO framework is built up from an alternating, vertex-sharing, network of ZnO4 and PO4 groups (d(av)(Zn-O) = 1.944 (8) Angstrom, d(av)(P-O) = 1.535 (9) Angstrom, theta(av)(Zn-O-P) = 130.5degrees) involving distinctive 4 = I secondary building units. The 1,2-diammonium propane cations are highly disordered in the [0 0 1] 8-ring channels. Crystal data: (CH3CH[NH3]CH2NH3)(1-2) . ZnPO4, M-r = 198.42, orthorhombic, space group Pnen (no. 52), a = 14.119 (6) Angstrom, b = 14.136 (5) Angstrom, c = 12.985 (5) Angstrom, V = 2591 (3) Angstrom(3), Z = 10, R(F) = 0.057, R-w(F) = 0.061 (for a twinned crystal).
