Abstract
The crystal structure of the title molecular salt, C5H11N3+·2Cl−, was redetermined. In comparison with the previous study [Bonnetet al.(1975).Bull. Soc. Fr. Mineral. Crist.98, 208–213.], the positions of some H atoms were corrected, allowing a more accurate description of the hydrogen-bonding scheme. In addition, the absolute structure was also determined. The maximum differences in terms of bond lengths and angles between the two determinations are 0.022 Å and 1.43°, respectively. The organic cation display aanticonformation of the protonated amine function and the imidazolium ring. The dihedral angle between the imidazolium plane and the plane through the C—C—N side chain is 29.58 (3)°. In the crystal, the organic cations and Cl−anions are stacked alternatively into layers parallel to (100). N—H...Cl hydrogen bonds between all H atoms of the ammonium group and both N—H groups of the imidazolium ring and the Cl−acceptor anions lead to the linkage of organic and inorganic layers into a three-dimensional network.
