3-Ethyl-4-[3-(1H-imidazol-1-yl)prop-yl]-5-phenyl-4H-1,2,4-triazole dihydrate.

ABSTRACT: In the title compound, C(16)H(19)N(5)·2H(2)O, the triazole ring makes dihedral angles of 70.61 (6) and 41.89 (8)°, respectively, with the imidazole and benzene rings. The water mol-ecules are involved in inter-molecular O-H⋯N and O-H⋯O hydrogen bonds, which stabilize the crystal packing.

3-(Adamantan-1-yl)-4-(prop-2-en-1-yl)-1H-1,2,4-triazole-5(4H)-thione.

Project description:The title mol-ecule, C(15)H(21)N(3)S, exists as the thione tautomer in the solid state. The 1,2,4-triazole ring is almost planar (r.m.s. deviation = 0.004?Å) and the prop-2-en-1-yl chain is close to being perpendicular to this plane [C-N-C-C torsion angle = 77.1?(5)°]. In the crystal, centrosymmetric dimeric aggregates are formed by pairs of N-H?S hydrogen bonds as parts of eight-membered (?HNCS)(2) synthons. These are connected into layers parallel to (101) via C-H?? inter-actions, where the ?-system is the triazole ring. The investigated sample was a nonmerohedral twin; the refined domain ratio was 0.655?(4):0.345?(4).

Crystal structure of 1-(1-methyl-1H-imidazol-2-yl)-4-phenyl-1H-1,2,3-triazole dihydrate.

Project description:The title compound, C12H11N5·2H2O, which crystallizes as a dihydrate, was obtained by Cu(I)-catalysed azide-alkyne cyclo-addition from 2-azido-1-methyl-imidazole and phenyl-ethyne. The dihedral angles between the central triazole ring (r.m.s. deviation = 0.004 Å) and the pendant imidazole (r.m.s. deviation = 0.006 Å) and phenyl rings are 12.3 (2) and 2.54 (19)°, respectively. In the crystal, the water mol-ecules are connected into [010] chains by O-H⋯O hydrogen bonds, while O-H⋯N hydrogen bonds connect the water mol-ecules to the organic mol-ecules, generating corrugated (100) sheets.

In the crystal structure, mol-ecules are hydrogen bonded via triazole NH groups and pyridyl N atoms, forming chains parallel to the a axis.

3-Benzyl-4-ethyl-1H-1,2,4-triazole-5(4H)-thione.

Project description:The title compound, C(11)H(13)N(3)S, exists in the 5-thioxo tautomeric form. The benzene ring exhibits disorder with a refined ratio of 0.77 (2):0.23 (2) for components A and B with a common bridgehead C atom. The 1,2,4-triazole ring is essentially planar, with a maximum deviation of 0.002 (3) Å for the benzyl-substituted C atom, and forms dihedral angles of 88.94 (18) and 86.56 (49)° with the benzene rings of components A and B, respectively. The angle between the plane of the ethyl chain and the mean plane of 1,2,4-triazole ring is 88.55 (15)° and this conformation is stabilized by an intra-molecular C-H⋯S contact. In the crystal, pairs of N-H⋯S hydrogen bonds link mol-ecules into inversion dimers. π-π inter-actions are observed between the triazole and benzene rings, with centroid-centroid separations of 3.547 (4) and 3.544 (12) Å for components A and B, and slippages of 0.49 (6) and 0.58 (15) Å, respectively.

5-Amino-3-(4H-1,2,4-triazol-4-yl)-1H-1,2,4-triazole.

Project description:The asymmetric unit of the title compound, C(4)H(5)N(7), comprises two independent but virtually superimposable mol-ecules. Each mol-ecule is planar with the dihedral angles between the five-membered rings being 2.8?(3) and 2.1?(3)°. The crystal structure is formed by an extensive network of relatively strong N-H?N hydrogen-bond inter-actions. Individual mol-ecules are arranged into supra-molecular zigzag chains running parallel to [001] by way of the strongest N-H?N inter-actions. Adjacent chains are inter-connected by rather long (D?A distances range from ca 3.00 to 3.03?Å) but highly directional (inter-action angles above ca 173°) hydrogen bonds forming a supra-molecular layer in the bc plane.
