Abstract
The title compound, C20H12Cl3N3O2, was synthesized by the reaction of 2-(2-hydroxyphenyl)benz[e][1,3]oxazin-4-one with 2,4,6-trichlorophenylhydrazine in ethanol. The trichlorophenyl ring is nearly perpendicular to the triazole plane [dihedral angle 80.56 (8)°], whereas the two hydroxyphenyl rings are approximately coplanar with the triazole ring [dihedral angles of 2.79 (12) and 8.00 (14)°]. Intramolecular O—H⋯N hydrogen bonding is observed between the hydroxyphenyl and triazole rings.
