N,N′-[4,4′-Methylenebis(4,1-phenylene)]bis(2,6-difluorobenzamide)

Abstract

The complete molecule of the title compound, C27H18F4N2O2, 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, molecules are connected by N—H...O and C—H...F hydrogen bonds, resulting in supramolecular chains propagating along the c direction.
