2,4-Dichloro-6-{[4-chloro-3-(trifluoromethyl)phenyl]iminomethyl}phenol

Abstract

Key indicators: single-crystal X-ray study; T = 298 K; mean (C-C) = 0.003 Å; R factor = 0.031; wR factor = 0.080; data-to-parameter ratio = 12.6.In the title Schiff base, C 14 H 7 Cl 3 F 3 NO, one intramolecular hydrogen bond stabilizes the molecular structure. The dihedral angle between the two benzene rings in the molecule is 47.86 (4) .
