In the title compound, C22H21N3O5, the β-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 molecules into infinite zigzag chains running parallel to the b axis.

Reflections (1 4 1), (0 3 2), (-1 2 2), (-2 0 2), (1 3 0) and (1 5 0) were omitted due to the large disagreement between Fobs and Fcalc. Owing to the poor quality of the crystal, the data obtained were rather poor and the value of Rint remained high (0.195).
2-Azetidinones, commonly known as β-lactams, constitute a most important class of antibiotics in both human and veterinary medicine (Arya et al., 2014; Singh & Sudheesh, 2014; Zeng et al., 2014; Zarei et al., 2013). In addition to their well recognized antibiotic activity, β-lactams exhibit various other biological activities such as thrombin, human, HIV-1 protease, human leukocyte elastase, cholesterol absorption inhibition and antifungal, anticancer, antidiabetic and potential antimalarial properties (Mehta et al., 2010; Singh et al., 2011; Ebrahimi & Jarrahpour, 2014). The synthesis and chemistry of spiro-fused 2-azetidinones has grown steadily over the years and many newly synthesized spiro-fused 2-azetidinones have been reported in the literature (Jarrahpour & Ebrahimi, 2010; Singh et al., 2011).
The β-lactam (azetidin-2-one) ring of the title compound (I, Fig. 1) is nearly planar, with a maximum deviation of -0.010 (1) Å for C1 from the mean plane. Atom O1 lies almost in the β-lactam plane, with a deviation of 0.069 (1) Å. The β-lactam ring makes a dihedral angle of 55.32 (5)° with the benzene ring C16—C21.
The xanthene ring system is V-shaped, with a dihedral angle between the (C4–C9) and (C10–C15) benzene rings of 19.07 (7)°. Its central ring, C2/C4/C9/O2/C10/C15, is not planar, with puckering parameters: QT = 0.2438 (13) Å, θ = 98.1 (3)° and φ = 2.0 (3)° (Cremer & Pople, 1975).
The mean plane of the xanthene ring system forms dihedral angles of 89.42 (4), 43.44 (3) and 22.80 (5)° (Nardelli, 1995), with the β-lactam ring, the benzene ring (C16–C21) and the least-squares plane formed by the four C atoms of the morpholine ring (N2/O5/C22–C25), respectively.
The bond lengths and angles in (I) are comparable with those observed in similar compounds that we have reported previously (Akkurt et al., 2008a,b; Çelik et al., 2009a,b; Çelik et al., 2014; Yalçın et al., 2009).

Geometry. Bond distances, angles etc. have been calculated using the rounded fractional coordinates. All su's are estimated from the variances of the (full) variance-covariance matrix. The cell e.s.d.'s are taken into account in the estimation of distances, angles and torsion angles |
Refinement. Refinement on F2 for ALL reflections except those flagged by the user for potential systematic errors. Weighted R-factors wR and all goodnesses of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The observed criterion of F2 > σ(F2) is used only for calculating -R-factor-obs etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

2-Azetidinones, commonly known as β-lactams, constitute a most important class of antibiotics in both human and veterinary medicine (Arya et al., 2014; Singh & Sudheesh, 2014; Zeng et al., 2014; Zarei et al., 2013). In addition to their well recognized antibiotic activity, β-lactams exhibit various other biological activities such as thrombin, human, HIV-1 protease, human leukocyte elastase, cholesterol absorption inhibition and antifungal, anticancer, antidiabetic and potential antimalarial properties (Mehta et al., 2010; Singh et al., 2011; Ebrahimi & Jarrahpour, 2014). The synthesis and chemistry of spiro-fused 2-azetidinones has grown steadily over the years and many newly synthesized spiro-fused 2-azetidinones have been reported in the literature (Jarrahpour & Ebrahimi, 2010; Singh et al., 2011).
The β-lactam (azetidin-2-one) ring of the title compound (I, Fig. 1) is nearly planar, with a maximum deviation of -0.010 (1) Å for C1 from the mean plane. Atom O1 lies almost in the β-lactam plane, with a deviation of 0.069 (1) Å. The β-lactam ring makes a dihedral angle of 55.32 (5)° with the benzene ring C16—C21.
The xanthene ring system is V-shaped, with a dihedral angle between the (C4–C9) and (C10–C15) benzene rings of 19.07 (7)°. Its central ring, C2/C4/C9/O2/C10/C15, is not planar, with puckering parameters: QT = 0.2438 (13) Å, θ = 98.1 (3)° and φ = 2.0 (3)° (Cremer & Pople, 1975).
The mean plane of the xanthene ring system forms dihedral angles of 89.42 (4), 43.44 (3) and 22.80 (5)° (Nardelli, 1995), with the β-lactam ring, the benzene ring (C16–C21) and the least-squares plane formed by the four C atoms of the morpholine ring (N2/O5/C22–C25), respectively.
The bond lengths and angles in (I) are comparable with those observed in similar compounds that we have reported previously (Akkurt et al., 2008a,b; Çelik et al., 2009a,b; Çelik et al., 2014; Yalçın et al., 2009).
In the crystal structure, molecules are linked by C—H···O hydrogen contacts (Table 1) into infinite zigzag chains running parallel to the b axis. Figs. 2, 3 and 4 show the projections along the a, b and c axes of the crystal packing of (I), respectively.
