N,N'-[4,4'-Methyl-enebis(4,1-phenyl-ene)]bis-(2,6-difluoro-benzamide).

The complete mol-ecule of the title compound, C(27)H(18)F(4)N(2)O(2), is generated by crystallographic twofold symmetry, with one C atom lying on the rotation axis. The dihedral angle between fluoro-substituted phenyl ring and the adjacent benzene ring is 10.37†(5)°. In the crystal, mol-ecules are connected by N-H⋯O and C-H⋯F hydrogen bonds, resulting in supra-molecular chains propagating along the c direction.
