title: (E)-1-{4-[Bis(4-fluoro-phen-yl)meth-yl]piperazin-1-yl}-3-(4-eth-oxy-phen-yl)prop-2-en-1-one.
abstract: In the title mol-ecule, C(28)H(28)F(2)N(2)O(2), 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 fluoro-benzene 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.
