title: 5-p-Tolyl-1,2,3,3a-tetra-hydro-benzo[e]pyrrolo-[2,1-b][1,3]oxazepin-10(5H)-one.
abstract: The structure of the title compound, C(19)H(19)NO(2), contains a seven-membered ring, which is fused to one five- and one six-membered ring, and carries a tolyl substituent. The two benzene rings are oriented relative to each other at a dihedral angle of 86.90 (7)°. In the crystal, mol-ecules are linked by weak inter-molecular C-H⋯O hydrogen bonds.
