چکیده
In the title compound, C(13)H(15)NO(2), the hexa-hydro-pyrrolo-[2,1-c][1,4]oxazine fragment is disordered over two conformations (A and B) in a 0.656 (5):0.344 (5) ratio. The five-membered ring is similarly disordered and adopts an envelope conformation in A, while in B this ring is nearly planar [maximum deviation = 0.088 (1) Å]. The six-membered rings in both A and B exhibit chair conformations. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into ribbons propagating in [010].

The mol-ecule of the title compound, C(13)H(9)NO(2), is slightly twisted with a dihedral angle of 4.85 (9)° between the nine-membered ring system and the phenyl ring. The nine non-H atoms of the 1H-pyrrolo[2,1-c][1,4]oxazin-1-one system are coplanar [r.m.s. deviation = 0.0122 (2) Å]. In the crystal, weak inter-molecular C-H⋯O inter-actions link mol-ecules into chains along [10]. The crystal stu...
