3,3′-(p-Phenylene)bis(3,4-dihydro-2H-1,3-benzoxazine)

Abstract

Molecules of the title compound, C22H20N2O2, are situated on crystallographic centres of symmetry. The oxazinane ring adopts a sofa conformation. Molecules are linked into cyclic centrosymmetric dimers via C—H...O hydrogen bonds with the motif R22(6). In addition to the C—H...O interactions, the crystal structure is also stabilized by C—H...π interactions.
