2-(1H-Benzotriazol-1-yl)-1-phenylethanol
In the title compound, C(14)H(13)N(3)O, the benzotriazole ring is oriented at a dihedral angle of 13.43 (4)° with respect to the phenyl ring. In the crystal structure, inter-molecular O-H⋯N hydrogen bonds link the mol-ecules into chains along the b axis. Aromatic π-π contacts between benzene rings and between triazole and benzene rings [centroid-centroid distances = 3.8133 (8) and 3.7810 (8) Å,...

In the title mol-ecule, C(23)H(19)N(3)O(3), the dihedral angles between the mean plane of the benzotriazole ring system and the benzene and phenyl rings are 9.67 (9) and 86.08 (10)°, respectively. The dihedral angle between the benzene and phenyl rings is 85.89 (11)°. In the crystal structure, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains along [010].

In the title compound, C(22)H(18)N(4)O(4), mol-ecules are linked to each other by C-H⋯N and C-H⋯O inter-molecular hydrogen-bonding inter-actions. The crystal packing is further stabilized by C-H⋯π, and π-π inter-actions with a distance of 3.783 (3) Å between the centroids of the benzene rings of the benzotriazole system.

In the title compound, C(22)H(16)BrN(3)O(3), the dihedral angles between the benzotriazole mean plane and the benzene rings of 4.84 (1) and 89.50 (1)°. The dihedral angle between the two benzene rings is 84.77 (1)°. In the crystal structure, mol-ecules are linked into chains by inter-molecular C-H⋯O hydrogen bonds. The crystal packing is further stabilized by C-H⋯π inter-actions.

The title compound, C(8)H(9)N(5)O, was synthesized by the reaction of ethyl 2-(benzotriazol-1-yl)acetate with hydrazine hydrate in ethanol. In the amide group, the C-N bond is relatively short [1.3283 (16) Å], suggesting some degree of electronic delocalization in the mol-ecule. In the crystal structure, mol-ecules are linked into infinite chains along the a axis by inter-molecular O-H⋯N hydrog...
