3-{[2-(Trifluoromethyl)phenyl]hydrazono}Pentane-2,4-dione

Abstract

The crystal structure of the title compound, C12H11F3N2O2, is stabilized by one N - H⋯O and two N - H⋯F intra-molecular hydrogen bonds, and by one C - H⋯F and two C - H⋯O inter-molecular 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 methyl groups and two F atoms of three trifluoromethyl groups, all atoms are almost in the same plane, and the N - N=C - C(OCH3) torsion angles are 4.1 (3) and -175.25 (14)°. © International Union of Crystallography 2007.
