title: N-(2-Fluoro-phen-yl)cinnamamide.
abstract: The title compound, C(15)H(12)FNO, was prepared by the reaction of cinnamoyl chloride with 4-fluoro-aniline and crystallizes with two mol-ecules A and B in the asymmetric unit. The two unique mol-ecules are closely similar and overlay with an r.m.s. deviation of 0.0819 Å. The fluoro-benzene and phenyl rings are inclined to one another at 73.89 (7) and 79.46 (7)°, respectively, in mol-ecules A and B. The amide C-N-C(O)-C portions of the mol-ecules are planar (r.m.s. deviations = 0.035 and 0.028 Å) and are inclined at 45.51 (9) and 47.71 (9), respectively, to the fluoro-benzene rings in mol-ecules A and B. The 2-fluoro-acetamide units and the benzene rings each adopt E configurations with respect to the C=C bonds. In the crystal structure, inter-molecular N-H⋯O hydrogen bonds augmented by weak C-H⋯π inter-actions link mol-ecules into rows in a head-to-tail fashion along a. Additional weak C-H⋯O contacts further stabilize the packing, forming a three-dimensional network stacked down a.
