Abstract

In the title compound, CHFNO, the conformation about the N-C-C-O bond is [torsion angle = 61.84 (13)°]. In the crystal, N-H⋯O hydrogen bonds link the mol-ecules into [010] chains, which are cross-linked by C-H⋯F and C-H⋯π contacts. Hirshfeld surface analysis was conducted to aid in the visualization of these various influences on the packing. This analysis showed that the largest contribution to the surface contacts arises from F⋯H/H⋯F inter-actions (35.6%), followed by O⋯H/H⋯O (17.8%) and H⋯H (12.7%).
