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 intra­molecular hydrogen bonds, and by one C—H⋯F and two C—H⋯O inter­molecular hydrogen bonds. These hydrogen bonds generate R44(13)S(6)S(6)S(6)R33(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)°.
