Abstract
In the title molecule, C28H28F2N2O2, the ethene bond exhibits an E conformation and the piperazine ring adopts a chair conformation. The amide-N atom of the piperazine ring is almost planar (bond-angle sum = 358.8°) whereas the other N atom is clearly pyramidal (bond-angle sum = 330.5°). The dihedral angle between the fluorobenzene rings is 76.36 (17)°. In the crystal, inversion dimers linked by pairs of C—H⋯O hydrogen bonds generate R 2 2(22) loops.

Summary
R factor = 0.060; wR factor = 0.187; data-to-parameter ratio = 14.4. Symmetry code: (i) x þ 1; y þ 1; z. C28H28F2N2O2, the ethene bond exhibits an E conformation and the piperazine ring adopts a chair conformation. The amide-N atom of the piperazine ring is almost planar (bond-angle sum = 358.8 ) whereas the other N atom is clearly pyramidal (bond-angle sum = 330.5 ). The dihedral angle between the fluorobenzene rings is 76.36 (17). Inversion dimers linked by pairs of C—H O hydrogen bonds generate R22(22) loops
