Two 1-phenyl-1H-imidazoles, 4-(1H-imidazol-1-yl)benzaldehyde and 1-(4-methoxyphenyl)-1H-imidazole, differ in the substituent para to the imidazole group on the arene ring. Both molecules pack with different motifs via similar weak C—H
N/O interactions and differ with respect to the angles between the mean planes of the imidazole and arene rings.

Three 2-substituted benzimidazole esters each exhibit different types of molecular disorder and different patterns of supramolecular assembly.

Three new 3-amino-2H-azirine derivatives have been synthesized as racemates or mixtures of diastereoisomers. Comparison of their crystal structures with those of the 11 other 3-amino-2H-azirines in the literature reveal that the formal N—C single bond in the azirine ring is consistently long at around 1.57 Å.

The structures of three distinct forms (cocrystal, salt and a hybrid cocrystal of salt) of multicomponent crystals of imidazole-based drugs (metronidazole, ketoconazole and miconazole) with trithiocyanuric acid as coformer are characterized. Their supramolecular architectures reflect the interplay between different molecular species.

The reactions of Cu(ClO4)2·6H2O and L′H in a variety of solvents have provided access to 12 solvatomorphs of the general formula [Cu(ClO4)2(LH)4]·x(solvent); the effect of the solvents on the packing of the complexes is critically discussed.

The title compounds are iron(II) dihalide complexes of the bulky arylimidazole ligand 1-(2,6-diisopropylphenyl)-1H-imidazole. The FeCl2 and FeBr2 complexes are isotypic, while the third compound, also an FeBr2 complex, crystallizes as a diethyl ether disolvate.

In the title salt, C6H12N3+·C7H3N2O7−, the imidazole ring is planar, with a maximum deviation of 0.0013 (14) Å for the N attached to the propanaminium group. In the anion, a single intramolecular O—HO hydrogen bond is observed. The mean planes of the nitro groups in the anion are twisted from the benzene ring mean plane making dihedral angles of 24.7 (9) and 3.9 (6)°. In the crystal, the ammonium H atoms form N—HN and N—HO hydrogen bonds, resulting in an infinite chain along [111]. In addition to the classical hydrogen bonds, weak C—HO and π–π [centroid–centroid distance = 3.7124 (9) Å] interactions are also observed, which lead to the formation a three-dimensional supramolecular structure that links the chains into layers along the bc plane.

In the title compound, C12H12N6·4H2O, the two triazole rings adopt a cis configuration with a crystallographic twofold axis passing through the central benzene group. The benzene and triazole rings are almost coplanar with a dihedral angle of 5.5 (1)°. In the crystal, water molecules are joined together by OW—HOW hydrogen bonds to form a one-dimensional zigzag chain. These water chains are further connected to the organic molecule, forming a three-dimensional network by intermolecular OW—HN and N—HOW hydrogen bonds. Moreover, π–π stacking interactions between triazole rings [centroid–centroid distances = 3.667 (1)–3.731 (1) Å] are observed. One of the water molecules shows one of the H atoms to be disordered over two positions.

The asymmetric unit of the title compound, C16H11FN2OS, comprises two independent molecules in which the benzothiazole rings are essentially planar, with maximum deviations of 0.038 (2) and 0.045 (3) Å. The central benzothiazole ring makes dihedral angles of 4.87 (13) and 0.64 (12)° and 4.04 (12) and 3.67 (12)° with the two terminal phenyl rings in the two independent molecules. In the crystal, molecules are connected via weak intermolecular C—HO hydrogen bonds forming supramolecular chains along the c axis.

The title compound, C23H21N3·C3H8O, crystallizes with two independent molecules and two solvent molecules in the asymmetric unit. These are connected through hydrogen bonds between the NH group of the imidazole ring and the O atom of the isopropanol solvent molecule, as well as between the N atom of the imidazole ring and the OH group of the isopropanol solvent molecule.
