The title compound, C(20)H(12)Cl(3)N(3)O(2), was synthesized by the reaction of 2-(2-hydroxy-phen-yl)benz[e][1,3]oxazin-4-one with 2,4,6-trichloro-phenyl-hydrazine in ethanol. The trichloro-phenyl ring is nearly perpendicular to the triazole plane [dihedral angle 80.56 (8)°], whereas the two hydroxy-phenyl rings are approximately coplanar with the triazole ring [dihedral angles of 2.79 (12) and...

In the title mol-ecule, C(17)H(10)F(3)N(3)O, the C=C bond connecting the triazole ring and 4-fluoro-phenyl groups adopts a Z conformation. The triazole ring forms dihedral angles of 15.3 (1) and 63.5 (1)°, with the 2,4-difluoro-substituted and 4-fluoro-substituted benzene rings, respectively. The dihedral angle between the two benzene rings is 51.8 (1)°.
