The title compound, C12H13N3O, exists in an E configuration with respect to the C=N bond [1.285 (2) Å]. The imidazole ring forms a dihedral angle of 75.97 (10)° with the phenyl ring. In the crystal, molecules are linked via O—HN and C—HN hydrogen bonds into sheets lying parallel to (001). The crystal structure also features C—Hπ interactions.

The title molecule, C15H21N3S, 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—HS hydrogen bonds as parts of eight-membered (HNCS)2 synthons. These are connected into layers parallel to (101) via C—Hπ interactions, where the π-system is the triazole ring. The investigated sample was a nonmerohedral twin; the refined domain ratio was 0.655 (4):0.345 (4).

The title molecule, C17H20N2O, is a functionalized hydrazine with benzoyl and adamantyl substituents attached to the two hydrazine N atoms. In the crystal, molecules are linked via N—HN hydrogen bonds, forming chains propagating along the a-axis direction. There are also C—HO, C—HN and C—Hπ interactions present within the chains.
