    Description / Table of Contents: Studies on Polyhalides. 26. On N-Propylurotropinium Polyiodides UrPrIx with x = 5 and 7: Crystal Structures of a Pentaiodide and a HeptaiodideThe salts UrPrIx with x = 5 and 7 are formed by the reaction of N-propylurotropinium iodide UrPrI with excess iodine I2 at room temperature from aqueous solution.

The crystal structure is built up from parallel chains of cations UrPr+ and pairs of V-shaped pentaiodide anions I5- along [0 1 0]. N-propylurotropinium heptaiodide C9H19N4I7 crystallizes triclinically in P1 with a = 970.4(1) pm, b = 971.1(1) pm, c = 1357.8(2) pm, α = 106.83(1)º, β = 92.28(1)º, γ = 105.17(1)º and Z = 2. The crystal structure is stacked by alternating cationic and anionic double layers along [0 0 1]. The heptaiodide layer shows a two-dimensional network.
