title: 1,3-Bis(4-methylphenyl)triazene, 1-(4-chlorophenyl)-3-(4-fluorophenyl)triazene and 1-(4-fluorophenyl)-3-(4-methylphenyl)triazene.
abstract: The title 4,4'-disubstituted diphenyl-1,3-triazines, C14H15N3, (I), C12H9ClFN3, (II), and C13H12FN3, (III), each contain a triazene group (-N=N-NH-) having an extended conformation. The dihedral angles between the two benzene rings in (I), (II) and (III) are 4.3, 3.4 and 6.5 degrees , respectively. The molecules are almost entirely planar, with maximum deviations from the mean planes of 0.1087 (2), -0.1072 (7) and 0.1401 (3) A, respectively. In each compound, the molecules are linked by N-H...N hydrogen bonds to form chains and pack similarly in the crystal structures.
