چکیده
The β-lactam (azetidin-2-one) ring of the title compound, C28H27N3O5, is nearly planar [maximum deviation = 0.010 (1) Å] and makes dihedral angles of 75.77 (5), 52.78 (9) and 88.72 (5)°, respectively, with the benzene ring, the least-squares plane formed by the four C atoms of the morpholine ring, which adopts a chair conformation, and the xanthene ring system. In the crystal, C-H⋯O hydrogen-bond contacts connect neighbouring mol-ecules into infinite zigzag chains running parallel to the b axis.

The title compound, C(37)H(27)NO(4), crystallizes with two mol-ecules in the asymmetric unit. The β-lactam ring of each mol-ecule is very nearly planar, with maximum deviations of 0.001 (2) and 0.017 (2) Å in the two mol-ecules. The crystal structure is stabilized by inter-molecular C-H⋯O and C-H⋯N contacts, as well as by weak C-H⋯π inter-actions.
