Abstract: | Two organically templated zincophosphites, (C6H14N2)·[Zn3(HPO3)4] and (C4H14N2)·[Zn3(HPO3)4] have been prepared under hydrothermal conditions and characterized by single-crystal X-ray diffraction. (C6H14N2)·[Zn3(HPO3)4] crystallizes in the triclinic space group , with cell parameters, a=9.363(4) Å, b=10.051(4) Å, c=10.051(4) Å, α=85.777(13)°, β=82.091(9)°, and γ=79.783(9)°. (C4H14N2)·[Zn3(HPO3)4] crystallizes in the monoclinic space group P21/c, with cell parameters, a=9.9512(3) Å, b=10.1508(3) Å, c=17.8105(5) Å, and β=95.6510(10)°. Although the two structures are different, they have the same anionic framework compositions of [Zn3(HPO3)4]2−. Their frameworks are built up from strictly alternating ZnO4 tetrahedra and HPO3 pseudo pyramids by sharing vertexes. There exist channels with an eight-membered ring window along the a- and c-axis. Powder X-ray diffraction, IR spectroscopy, 31P MAS solid-state NMR, thermogravimetric and differential thermal analyses were also carried out. |
