"The title compound, C18H20N2O2, was prepared by Mannichtype reaction of phenol, ethane-1,2-diamine and formaldehyde. The heterocyclic rings adopt half-chair conformations. The acyclic methylene groups attached to the N atoms are in an axial position. In the crystal, weak C-H...O hydrogen bonds link the molecules into dimers. These dimers are further connected via C-H...pi contacts."@en . . . "10"^^ . "crystal structure; X-ray diffraction; Jana2006; oxazine"@en .
