The title complex, [Co(C2N3)2(C7H6N4)2(H2O)2] or [Co(dca)2(pytrz)2(H2O)2], where pytrz is 4-(2-pyridyl)-4H-1,2,4-triazole and dca is the dicyanamide monoanion, was prepared using pytrz, Na(dca) and CoCl2·6H2O. The CoII atom lies on a center of inversion and is coordinated in a slightly distorted octahderal geometry by two pytrz ligands, two dca ligands and two trans-oriented water molecules. In the crystal structure, complex molecules are linked by O—H...N hydrogen bonds into a two-dimensional network and further into a three-dimensional network via weak C—H...N hydrogen bonds.

In the title compound, C14H12Br4N2, the molecule lies across an inversion center and hence the benzene rings are strictly coplanar. In the crystal, molecules are linked by N—H...N and weak N—H...Br hydrogen bonds, forming a two-dimensional network parallel to (101). In addition, type II Br...Br interactions [3.625 (4) Å] complete a three-dimensional supramolecular network.

The asymmetric unit of the title salt, [H3N(CH2)6NH3][(HO)O2P(CH2)6PO2(OH)], consists of one half of a hexane-1,6-diaminium dication and one half of a hexane-1,6-diyl bis(hydrogen phosphonate) dianion. Both are located around different centres of inversion (Wyckoff sites: 2aand 2d) of the space groupP21/c. The shape of the hexane-1,6-diaminium cation is best described as a double hook. Both aminium groups as well as the two attached CH2groups are turned out from the plane of the central four C atoms. In contrast, all six C atoms of the dianion are almost in a plane. The hydrogen phosphonate (–PO3H) groups of the anions and the aminium groups of the cations form two-dimensional O—H... and O—H...N hydrogen-bonded networks parallel to theacplane, built up from ten-membered and twelve-membered ring motifs with graph-set descriptorsR33(10) andR54(12), respectively. These networks are linked by the alkylene chains of the anions and cations. The resulting three-dimensional network shows a herringbone pattern, which resembles the parent structures 1,6-diaminohexane and hexane-1,6-diphosphonic acid.

An example of a 4,4'-bipyridine ( γbpy ) clathrate in its copper(II) complex has been established. The compound, [Cu( γbpy )(H2O)2(ClO4)2]n.( γbpy )n, crystallizes in the monoclinic space group C2/c with a 16.651(3), b 11.089(2), c 14.360(3) Ǻ, β 116.45(3)°, V 2373.9(8)Ǻ3. The crystal structure comprises γbpy -bridged linear polymeric [Cu( γbpy )(H2O)2(ClO4)2]n chains, where the copper atom, located on a crystallographic twofold axis, is coordinated in an elongated octahedral environment by two nitrogen atoms of the bridging γbpy ligands (Cu-N 1.998(4)Ǻ) and two water molecules (Cu-O 1.968(3)Ǻ) at the equatorial positions, and two perchlorate oxygen atoms at the axial positions (Cu-O 2.414(4)Ǻ). The chains are interconnected by hydrogen bonds between the aqua ligands and the uncoordinated perchlorate oxygen atoms to form two-dimensional layers with cavities each enclosing a γbpy molecule. Hydrogen bonding between the aqua ligands and the nitrogen atoms of the solvate γbpy molecules further extends the structure into a three-dimensional network in the solid.

The crystal structure of the title salt {systematic name: [1,3-phenylenebis(methylene)]bis(azanium) sulfate}, C8H14N22+·SO42−, consists of infinite (100) sheets of alternating organic and inorganic entities Them-xylylenediaminium cations are linked to the sulfate anions by N—H...O and asymmetric bifurcated N—H...(O,O) hydrogen bonds, generating a three-dimensional network. A weak C—H...O interaction also occurs. The Hirshfeld surface analysis and the two-dimensional fingerprint maps indicate that the packing is dominated by H...O/O...H and H...H contacts.

In the redetermination of the title compound, C3H5N2OS+·CI−, the asymmetric unit consists of one independent 2-oxo-1,3-thiazolidin-4-iminium cation and one independent chloride anion. The cation interacts with a chloride anion via N—H...Cl hydrogen bonds forming a supramolecular chain along [010]. These supramolecular chains are further extended by weak C—H...Cl and C—H...O interactions, forming a two-dimensional network parallel to (001). The crystal structure is further stabilized by weak C—O...π interactions, supporting a three-dimensional architecture. The structure was previously determined by Ananthamurthy & Murthy [Z. Kristallogr. (1975). 8, 356–367] but has been redetermined with higher precision to allow the hydrogen-bonding patterns and supramolecular interactions to be investigated.

In the title compound, C16H14N2O3S, the 1,3-benzoxazole ring system is essentially planar (r.m.s deviation = 0.004 Å) and makes a dihedral angle of 66.16 (17)° with the benzene ring of the methoxyphenyl group. Two intramolecular N—H...O and N—H...N hydrogen bonds occur, forming S(5) and S(7) ring motifs, respectively. In the crystal, pairs of C—H...O hydrogen bonds link the molecules into inversion dimers with R 2 2(14) ring motifs, stacked along the b-axis direction. The inversion dimers are linked by C—H...π and π–π-stacking interactions [centroid-to-centroid distances = 3.631 (2) and 3.631 (2) Å], forming a three-dimensional network. Two-dimensional fingerprint plots associated with the Hirshfeld surface show that the largest contributions to the crystal packing come from H...H (39.3%), C...H/H...C (18.0%), O...H/H...O (15.6) and S...H/H...S (10.2%) interactions.

The condensation of 2-furoic hydrazide and 4-dimethyl aminobenzaldehyde in ethanol yielded a yellow solid formulated as the title compound, C14H15N3O2·H2O. The crystal packing is stabilized by intermolecular O(water)—H...O,N(carbohydrazide) and N—H...O(water) hydrogen bonds, which form a two-dimensional network along the bc plane. Additional C—H...O interactions link the molecules into a three-dimensional network. The dihedral angle between the mean planes of the benzene and the furan ring is 34.47 (6)°. The carbohydrazide moiety, i.e., the C=N—N—C=O fragment and the benzene ring are almost coplanar, with an angle of 6.75 (9)° between their mean planes.

Crystals of bis(2-ethyl-3-hydroxy-6-methylpyridinium) succinate–succinic acid (1/1), C8H12NO+·0.5C4H4O42−·0.5C4H6O4, (I), and 2-ethyl-3-hydroxy-6-methylpyridinium hydrogen succinate, C8H12NO+·C4H5O4−, (II), were obtained by reaction of 2-ethyl-6-methylpyridin-3-ol with succinic acid. The succinate anion and succinic acid molecule in (I) are located about centres of inversion. Intermolecular O—H...O, N—H...O and C—H...O hydrogen bonds are responsible for the formation of a three-dimensional network in the crystal structure of (I) and a two-dimensional network in the crystal structure of (II). Both structures are additionally stabilized by π–π interactions between symmetry-related pyridine rings, forming a rod-like cationic arrangement for (I) and cationic dimers for (II).
