The solid-state structure of the title compound, C~32~H~40~N~2~O~2~, is characterized by benzoxazine units with a __cisoid__ geometry, and with the N atoms displaced from the planes of the heterocycles. The two benzoxazine groups are nearly coplanar.
The title compound, C 20 H 18 N 4 O 2 Á2H 2 O, an amide-containing bipyridyl-type compound, crystallizes as a dihydrate. The organic molecule is centrosymmetric. Hydrogen-bonding and stacking interactions in the crystal structure result in the formation of an infinite three-dimensional supramolecula
