The non-H atoms of the title molecule, C10H10N2O, are essentially coplanar, with a maximum deviation of 0.046 (4) Å for the O atom. In the crystal, molecules are linked by weak C—H...O hydrogen bonds, forming chains along [010]. In addtion, weak C—H...π interactions and π–π stacking interactions between benzene and pyrimidine rings, with a centroid–centroid distance of 3.730 (3) Å, link the chains, forming a two-dimensional network parallel to (001).

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 mixed-ligand metal–organic complex poly[(μ3-phthalato)[μ2-3-(pyridin-2-yl)-1H-pyrazol-1-ido]dicopper(II)], [Cu2(C8H4O4)(C8H6N3)2]n, has been synthesized by the reaction of copper(II) acetate with 2-(1H-pyrazol-3-yl)pyridine (HL) and phthalic acid. The binuclear chelating–bridgingLunits are further linked by bridging phthalate ligands into a two-dimensional network parallel to the (010) plane. The two-dimensional networks are extended into a three-dimensional supramolecular architectureviaπ–π stacking interactions.

In the title molecular structure, C14H15NO4, all non-H atoms, except for the C atoms of the terminal methyl groups of the diethylamino substituents, are essentially coplanar. In the crystal structure, a two-dimensional network is formed via weak intermolecular C—H...O hydrogen bonds and π–π stacking interactions.

In the molecule of the title compound, [Cu(C10H8N2)(C4H2O4)(H2O)]·2H2O, the Cu(II) atom has elongated tetragonal pyramidal geometry, coordinated by one water O atom, two N atoms of the 2,2′-bipyridine ligand and two O atoms of the two carboxylate groups of the maleate dianion. The molecules are linked through hydrogen-bonding and π–π stacking interactions, forming a two-dimensional supramolecular structure.

In the title mononuclear complex, [Ni(C3H2O4)(C15H10N4)(H2O)]·3H2O, the metal center is coordinated in a distorted NiN3O3geometry. In the crystal structure, intermolecular O—H...O hydrogen bonds link the components into a two-dimensional network. In addition, there are weak π–π stacking interactions between symmetry-related phenanthroline rings, with a centroid–centroid distance of 3.6253 (17) Å.

The asymmetric unit of the title compound, 2C5H3ClO2S·C10H8N2, is comprised of a molecule of 3-chlorothiophene-2-carboxylic acid (3TPC) and half of a molecule of 4,4′-bipyridine (BPY). A distinctive O—H...N-based synthon is present. Cl...Cl and π–π stacking interactions further stabilize the crystal structure, forming a two-dimensional network parallel to thebcplane.

New complexes containing the 1,4-bis(pyridazin-4-yl)benzene ligand, namely diaquatetrakis[1,4-bis(pyridazin-4-yl)benzene-κN2]cadmium(II) hexaiodidodicadmate(II), [Cd(C14H10N4)4(H2O)2][Cd2I6], (I), and poly[[μ-1,4-bis(pyridazin-4-yl)benzene-κ2N2:N2′]bis(μ-thiocyanato-κ2N:S)cadmium(II)], [Cd(NCS)2(C14H10N4)]n, (II), demonstrate the adaptability of the coordination geometries towards the demands of slipped π–π stacking interactions between the extended organic ligands. In (I), the discrete cationic [Cd—N = 2.408 (3) and 2.413 (3) Å] and anionic [Cd—I = 2.709 (2)–3.1201 (14) Å] entities are situated across centres of inversion. The cations associateviacomplementary O—H...N2′hydrogen bonding [O...N = 2.748 (4) and 2.765 (4) Å] and extensive triple π–π stacking interactions between pairs of pyridazine and phenylene rings [centroid–centroid distances (CCD) = 3.782 (4)–4.286 (3) Å] to yield two-dimensional square nets. The [Cd2I6]2−anions reside in channels generated by packing of successive nets. In (II), the CdIIcation lies on a centre of inversion and the ligand is situated across a centre of inversion. A two-dimensional coordination array is formed by crosslinking of linear [Cd(μ-NCS)2]nchains [Cd—N = 2.3004 (14) Å and Cd—S = 2.7804 (5) Å] withN2:N2′-bidentate organic bridges [Cd—N = 2.3893 (12) Å], which generate π–π stacks by double-slipped interactions between phenylene and pyridazine rings [CCD = 3.721 (2) Å].

In the title hydrated molecular salt, C38H52N42+·2Br−·H2O, the central benzene ring of the dication makes dihedral angles of 89.47 (13) and 72.69 (12)° with the pendant benzimidazol-3-ium rings. The conformations of the octyl side chains are completely different. In the crystal, the components are linked by O—H...Br, C—H...Br and C—H...O hydrogen bonds into a two-dimensional network lying parallel to theacplane. Aromatic π–π stacking interactions are also observed [shortest centroid-to-centroid separation = 3.5047 (16) Å].
