Abstract

Two new organically templated zinc phosphites, [H3N(CH 2)4NH3]·[Zn3(HPO 3)4]·H2O (1) and [C3N 2H5]2· [Zn3(HPO 3)4] (2) have been synthesized under mild hydrothermal conditions. Their structures were determined by single-crystal X-ray diffraction and further characterized by FTIR, elemental analysis, inductively coupled plasma (ICP) analysis, powder X-ray diffraction, and thermogravimetric analysis. In addition to the same anionic framework compositions of [Zn 3(HPO3)4]2-, both phases consist of strictly alternating ZnO4 tetrahedra and HPO3 pseudo-pyramids linked through their vertexes to generate the three-dimensional frameworks with intersecting 8- and 12-membered ring channels, where the template molecules reside. Compound 1 crystallizes in the triclinic system, space group P1 with the following cell parameters: a = 7.7703(4) Å; b = 9.1499(4) Å; c = 14.4685(3) Å; α = 89.965(2)°; β = 87.050(2)°; γ = 65.332(2)°; V = 933.31(7) Å3; Z = 2. Compound 2 crystallizes in the triclinic system, space group P1 with the following cell parameters: a = 9.0238(4) Å; b = 9.0392(4) Å; c = 13.8071(6) Å; α = 95.965(2)°; β = 96.049-(2)°; γ = 110.228(2)°; V = 1038.92 (8) Å3; Z = 2.
