3,3'-(Ethane-1,2-di-yl)bis-(3,4-dihydro-2H-1,3-benzoxazine).

ABSTRACT: The title compound, C(18)H(20)N(2)O(2), was prepared by Mannich-type reaction of phenol, ethane-1,2-diamine and formaldehyde. The heterocyclic rings adopt half-chair conformations. The acyclic methyl-ene groups attached to the N atoms are in an axial position. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into dimers. These dimers are further connected via C-H⋯π contacts.
