In the structure of the brucinium salt of 4-aminophenylarsonic acid (p-arsanilic acid), systematically 2,3-dimethoxy-10-oxostrychnidinium 4-aminophenylarsonate tetrahydrate, (C23H27N2O4)[As(C6H7N)O2(OH)]·4H2O, the brucinium cations form the characteristic undulating and overlapping head-to-tail layered brucine substructures packed along [010]. 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.

The title compound, C18H17NO4, was obtained accidentally through acid-catalysed aromatization of a phthalimide-substituted 2-(1-hydroxyethyl)cyclohex-2-enone. It exhibits an intramolecular O—H...Oc (c = carbonyl) hydrogen bond and forms a three-dimensional network structure via π–π stacking interactions between adjacent benzene rings (phthalimide-to-phenylene and phthalimide-to-phthalimide), with centroid–centroid distances of 3.8262 (6) and 3.6245 (5) Å.

Reduction of bicyclo[3.3.0]octane-3,7-dione yields a mixture of the endo-3,endo-7-diol and endo-3, exo-7-diol (C8H14O2) isomers (5 and 6). These form (5)2·(6) co-crystals in the monoclinic P21/n space group (with Z = 6, Z′ = 1.5) rather than undergoing separation by means of fractional recrystallization or column chromatography. The molecule of 5 occupies a general position, whereas the molecule of 6 is disordered over two orientations across a centre of symmetry with occupancies of 0.463 (2) and 0.037 (2). Individual diol hydroxy groups associate around a pseudo-threefold screw axis by means of hydrogen bonding. The second hydroxy group of each diol behaves in a similar manner, generating a three-dimensional hydrogen-bonded network structure. This hydrogen-bond connectivity is identical to that present in three known helical tubuland diol–hydroquinone co-crystals, and the new crystal structure is even more similar to two homologous aliphatic diol co-crystals.

In the title compound, C18H12O4, the essentially planar chromenone ring system [the maximum deviation = 0.016 (2) Å] is nearly co-planar with the phenyl ring [dihedral angle = 3.85 (8)°]. An intramolecular O—H...O hydrogen bond occurs. In the crystal, weak C—H...O hydrogen bonds and π–π stacking interactions link the molecules into a three-dimensional supramolecular network.

The conformation about the central benzene ring in the molecule of (I), C20H19N3O2, is partially determined by an intramolecular N—H...O hydrogen bond. In the crystal, chains parallel to the c axis are generated by intermolecular N—H...O hydrogen bonds with the chains assembled into a three-dimensional network structure by intermolecular C—H...O hydrogen bonds and C—H...π(ring) interactions. The molecule of (II), C22H21N3O, differs from (I) only in the substituent at the hydrazide N atom where a phenylmethylene moiety for (II) is present instead of a furanmethylene moiety for (I). Hence, molecules of (I) and (II) show similarities in their molecular and crystal structures. The conformation of the central portion of the molecule of (II) is also therefore partially determined by an intramolecular N—H...O hydrogen bond and intermolecular N—H...O hydrogen bonds form chains parallel to the c axis. Likewise, the chains are connected into a three-dimensional network by C—H...O hydrogen bonds and C—H...π(ring) interactions.
