In the mol-ecule of the title compound, C(23)H(18)ClN(3)O(3), the essentially planar benzotriazole ring makes dihedral angles of 52.93 (1) and 85.21 (1)°, respectively, with the chloro-phenyl and tolyl rings. The crystal packing is stabilized by π-π [centroid-to-centroid distance 3.830 (2) Å, interplanar distance 3.705 Å, slippage 0.968 Å]; C-H⋯π⋯tolyl ring inter-actions are also present.

New 6-CF3-1H-pyrazolo[3,4-b]quinolines with a methyl and/or phenyl group attached to the pyrazole core (Molx (x = 1, 2, 3, 4)) were synthesized and characterized in terms of their optoelectronic applications: photovoltaic electroluminescence. The fluorescence emissions investigated phenyl-decorated pyrazoloquinolines is caused by photoinduced charge transfer p process occurring between substitu...

In the title compound, C(31)H(28)N(2)O, the dihedral angles formed by the imidazole ring with the three aryl substituents are 18.52 (8) and 85.56 (7) and 85.57 (7)°, respectively. In the crystal, mol-ecules are linked by O-H⋯N and C-H⋯O hydrogen bonds into chains parallel to the a axis.

In the title compound, C(8)H(8)N(4)·C(8)H(8)N(4), two tautomers, viz. 3-phenyl-1,2,4-triazol-5-amine and 5-phenyl-1,2,4-triazol-3-amine, are crystallized together in equal amounts. The 3-phenyl-1,2,4-triazol-5-amine mol-ecule is essentially planar; the phenyl ring makes a dihedral angle of 2.3 (2)° with the mean plane of the 1,2,4-triazole ring. In the 5-phenyl-1,2,4-triazol-3-amine tautomer, t...
