title: 3,3'-(p-Phenyl-ene)bis-(3,4-dihydro-2H-1,3-benzoxazine).
abstract: Mol-ecules of the title compound, C(22)H(20)N(2)O(2), are situated on crystallographic centres of symmetry. The oxazinane ring adopts a sofa conformation. Mol-ecules are linked into cyclic centrosymmetric dimers via C-H⋯O hydrogen bonds with the motif R(2) (2)(6). In addition to the C-H⋯O inter-actions, the crystal structure is also stabilized by C-H⋯π inter-actions.
