The title fluorinated bisbenzoxazine, C18H18F2N2O2, crystallizes with one half-molecule in the asymmetric unit, which is completed by inversion symmetry. The fused oxazine ring adopts an approximately half-chair conformation. The two benzoxazine rings are oriented anti to one another around the central C-C bond. The dominant intermolecular interaction in the crystal structure is a C-H...F hydrogen bond between the F atoms and the axial H atoms of the OCH2N methylene group in the oxazine rings of neighbouring molecules. C-H...[pi] contacts further stabilize the crystal packing.
