1-(Morpholin-4-yl)-4-(2-nitro-phen-yl)spiro-[azetidine-3,9'-xanthen]-2-one.

ABSTRACT: In the title compound, C22H21N3O5, the ?-lactam (azetidin-2-one) ring is nearly planar [maximum deviation = 0.010?(1)?Å] and makes dihedral angles of 69.22?(5), 55.32?(5) and 89.42?(4)° with the least-squares planes formed by the four C atoms of the morpholine ring, which adopts a chair conformation, the benzene ring and the xanthene ring system, respectively. In the crystal, C-H?O hydrogen-bond contacts connect neighbouring mol-ecules into infinite zigzag chains running parallel to the b axis.
