N2 - Two organically templated zinc phosphites, (C2N 2H10)Zn2(HPO3)3 (1) and (C4N2H12)Zn3(HPO3) 4 (2), were hydrothermally synthesized and structurally characterized. Compound 1 crystallized in the triclinic system, space group P-1 (No. 2), a=8.6357(14) Å, b=8.8197(14) Å, c=9.9665(16) Å, α=64.645(2), β=65.922(2), γ=81.049(2)°, V=626.12(17) Å3, Z=2. The connectivity of the strictly alternating ZnO 4 and HPO3 polyhedra results in infinite macroanionic layers with 4.8-net. The organic cations locate in the interlayer region and hold the macroanionic sheets together by strong H-bonds. Compound 2 crystallized in the monoclinic system, space group P21/c (No. 14), a=9.9352(14) Å, b=10.1487(14) Å, c=17.8257(13) Å, β=95.701(7), V=1788.5(4) Å3, Z=4. The structure of 2 consists of ZnO4 tetrahedra and HPO3 pseudo-pyramids with shared vertices, forming a 3D framework with 8-ring channels. Both compounds were characterized by FTIR, elemental analysis, ICP analysis and thermogravimetric analysis.
