In the crystal structure of the title organic proton-transfer complex, 2C12H11N2 +·C7H4O5S2−·3H2O, the cations form one-dimensional chains via intermolecular N—H...N hydrogen bonds and these chains, in turn, form a two-dimensional network through π–π stacking interactions. In addition, the anions and water molecules are connected into a two-dimensional hydrogen-bonded network through intermolecular O—H...O hydrogen bonds. The two motifs result in sheets of cations and anions stacked alternately.

The title compound, C2H10N2 2+·2Cl−·2C12H8N2·4H2O, has an inversion centre located midway between the two C atoms of the ethylenediammonium cation. The 1,10-phenanthroline molecules stack along the a axis, and are linked by π–π stacking interactions to form one-dimensional chains. These are bridged by ethylenediammonium cations, via hydrogen bonds, forming two-dimensional supramolecular sheets parallel to the ac plane. Hydrogen bonds to chloride anions and water molecules connect these two-dimensional sheets, resulting in the formation of a three-dimensional supramolecular network.

In an attempt to brominate 1,4-dipropoxy-9,10-anthraquinone, a mixture of products, including the title compound, C14H7BrO4, was obtained. The molecule is essentially planar (r.m.s. deviation = 0.029 Å) and two intramolecular O—H...O hydrogen bonds occur. In the crystal, the molecules are linked by weak C—H...O hydrogen bonds, Br...O contacts [3.240 (5) Å], and π–π stacking interactions [shortest centroid–centroid separation = 3.562 (4) Å], generating a three-dimensional network.

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).

The arsanilate anions and the water molecules of solvation are accommodated between the layers and are linked to them through a primary cation N—H...O(anion) hydrogen bond, as well as through water O—H...O hydrogen bonds to brucinium and arsanilate ions as well as bridging water O-atom acceptors, giving an overall three-dimensional network structure.
