Key indicators: single-crystal X-ray study; T = 296 K; mean (C-C) = 0.003 Å; R factor = 0.044; wR factor = 0.145; data-to-parameter ratio = 13.6. The crystal structure of the title compound, C 12 H 11 F 3 N 2 O 2 , is stabilized by one N-HÁ Á ÁO and two N-HÁ Á ÁF intramolecular hydrogen bonds, and by one C-HÁ Á ÁF and two C-HÁ Á ÁO intermolecular hydrogen bonds. These hydrogen bonds generate R 4 4 (13)S(6)S(6)S(6)R 3 3 (20) ring motifs in the ac plane. Except for four H atoms of the methyldoi:10.1107/s1600536807045631 fatcat:btv3d4pvazahdm6danmefngfxe
