The crystal structure of DL-alanine hydroiodide (1-carboxyethanaminium iodide), C3H8NO2 +·I−, is that of an organic salt consisting of N-protonated cations and iodide anions. The compound features homochiral helices of N—H...O hydrogen-bonded cations in the [010] direction; neighbouring chains are related by crystallographic inversion centers and hence show opposite chirality. The iodide counter-anions act as hydrogen-bond acceptors towards H atoms of the ammonium and carboxy groups, and cross-link the chains along [100]. Thus, an overall two-dimensional network is formed in the ab plane. No short contacts occur between iodide anions.

6-Chloro-9-propyl-purin-2-amine (pr-GCl) forms two-dimensional hydrogen-bonded networks which in turn stack via π–π interactions, leading to the formation of bilayers that can accommodate organic guest molecules.

Six ammonium carboxylate salts, namely cyclopentylammonium cinnamate, C5H12N+·C9H7O2−, (I), cyclohexylammonium cinnamate, C6H14N+·C9H7O2−, (II), cycloheptylammonium cinnamate form I, C7H16N+·C9H7O2−, (IIIa), and form II, (IIIb), cyclooctylammonium cinnamate, C8H18N+·C9H7O2−, (IV), and cyclododecylammonium cinnamate, C12H26N+·C9H7O2−, (V), are reported. Salts (II)–(V) all have a 1:1 ratio of cation to anion and feature three N+—H...O−hydrogen bonds forming one-dimensional hydrogen-bonded columns consisting of repeatingR43(10) rings, while salt (I) has a two-dimensional network made up of alternatingR44(12) andR68(20) rings. Salt (III) consists of two polymorphic forms,viz.form I havingZ′ = 1 and form II withZ′ = 2. The latter polymorph has disorder of the cycloheptane rings in the two cations, as well as whole-molecule disorder of one of the cinnamate anions. A similar, but ordered,Z′ = 2 structure is seen in salt (IV).
