(Received 21 December 2010; accepted 5 January 2011; online 12 January 2011)

The central β-lactam ring of the title compound, C23H21NO3, is almost planar (r.m.s. deviation = 0.032Å). The meth­oxy­benzene ring is almost coplanar with the β-lactam ring [dihedral angle = 1.87 (11)°], whereas the tolyl ring is almost normal to it [75.73 (12)°]. The dihedral angle between the β-lactam ring and the O-bonded phenyl ring is 51.95 (12)°. An intra­molecular C—H⋯O inter­action generates an S(6) ring. The crystal structure features inter­molecular C—H⋯O hydrogen bonds, forming layers parallel to (011), and weak C—H⋯π inter­actions. Two aromatic ππ stacking inter­actions [centroid–centroid distances = 3.6744 (12) and 3.6799 (11) Å] are also observed.

Supporting information


Comment top

The title compound, (I), is a β-lactam derivative with potential biological properties (Jarrahpour & Zarei, 2010); we now describe its crystal structure. In the title compound (I), (Fig. 1), the β-lactam ring (N1/C7–C9) is nearly planar [r.m.s. deviation = 0.032Å]. The dihedral angles between the planes of the rings in (I) are given in Table 2. The molecular dimensions are normal and lie within expected values for corresponding bond distances and angles (Allen et al., 1987).

The molecular structure is stabilized by intramolecular C—H···O hydrogen bonds, forming an S(6) graph-set motif (Bernstein et al., 1995) (Table 1). In the crystal structure, molecules are linked via intermolecular C—H···O hydrogen bonds (Table 1, Fig. 2), forming layers parallel to the bc plane. In addition, C—H···π interactions and two π-π stacking interactions [Cg1···Cg3(x, y, z) = 3.6744 (12) Å and Cg4···Cg4(1 - x, 2 - y, 1 - z) = 3.6799 (11) Å, where Cg1, Cg3 and Cg4 are the centroids of the N1/C7–C9 β-lactam, the C10–C15 and C17–C22 benzene rings, respectively] contribute to the stabilization of the structure.

The title compound was prepared as described by Jarrahpour & Zarei (2010) and colourless prisms of (I) were recrystallized from ethyl acetate.

Refinement top

All H atoms were placed at calculated positions and were treated as riding on their parent atoms with C—H = 0.93 (aromatic), 0.96(methyl) and 0.98 Å (methine), and with Uiso(H) = 1.5Ueq(C) for methyl and Uiso(H) = 1.2Ueq(C) for aromatic, methine.

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.
