The cyclo-propylammonium cation as a templating agent for inorganic networks: synthesis and structure of (C3H8N)(2)center dot Zn-3(HPO3)(4)

The hydrothermal synthesis and single crystal structure of (C3H8N)(2)center dot Zn-3(HPO3)(4) are described. This compound is built up from ZnO4 tetrahedra and HPO3 pyramids sharing vertices to generate a three-dimensional 4:3 network containing 8-ring channels. The protonated organic cations occupy the channels in a head-to-tail arrangement and interact with the framework by way of N-H center dot center dot center dot O hydrogen bonds. Crystal data: C6H20N2O12P4Zn3, M-r = 632.23, monoclinic, P2(1)/n (No. 14), Z = 4, a = 9.6773 (2) angstrom, b = 13.8676 (2) angstrom, c = 15.4482 (3) angstrom, beta = 90.039 (1)degrees, V = 2073.16 (7) angstrom(3), R(F) = 0.028, wR(F-2) = 0.062.
