In the title compound, C28H19NO4, the con®gurations of the substituents attached to the oxirane ring are conditioned by the sp3 states of the oxirane C atoms. In the packing, the molecules form zigzag molecular chains along thebdirection.
Comment
Photoinduced oxygenation reactions of indolizine derivatives have been investigated intensively in our previous study (Tian
et al., 2001). In continuation of that work, we have isolated the title compound, (I), which was obtained from the photo-oxy-genation reactions of 1,3-dibenzoyl-2-phenylindolizine. We report here an X-ray crystallographic analysis at 213 K of (I), which was undertaken to establish its conformation and stereochemistry.
The bond lengths and angles observed in (I) (Fig. 1) are within normal ranges (Allenet al., 1987). The values within the oxirane (O3/C9/C16) agree with those of a related structure studied previously (Krishnakumar et al., 2002), except for a slight elongation of the C9ÐC16 bond [1.509 (3) AÊ versus
1.488 (4) AÊ (Krishnakumar et al., 2002)] due to the bulky substituents attached at atoms C9 and C16. The con®gurations

of the substituents are conditioned by these twosp3 atoms. Except for the bond angles within the oxirane, the average bond angles subtended at atoms C9 and C16 are 117.2 and 116.8, respectively, while the two atoms are eclipsed, as
determined by the torsion angles C8ÐC9ÐC16ÐC17 = 1.4 (3)and C10ÐC9ÐC16ÐC22 = 4.7 (3).
In the dioxophenylethylene moiety (O1/O2/C1±C9), the two carbonyl groups form O1/C6/C7/C8 and O2/C7/C8/C9 planes. These two planes are twisted out of the phenyl ring by 11.7 (1) and 38.8 (1), respectively. The O2/C7/C8/C9 plane
and the C10±C15 phenyl ring attached at atom C9 form dihedral angles of 56.1 (1) and 63.6 (2), respectivley, with the
oxirane ring plane.
The pyridine ring (N1/C17±C21) attached at atom C16 is perpendicular to the oxirane ring plane, with a dihedral angle of 88.6 (2). The carbonyl group of the benzoyl moiety (O4/
C22±C28) attached at the same atom is twisted from its aromatic ring by an angle of 20.8 (1)and the O4/C16/C22/C23
plane makes a dihedral angle of 61.8 (2)with the oxirane ring
plane.
In the packing, the molecules are interconnected by C21Ð H21 O4i interactions [H21 O4i 2.56 AÊ and C21Ð H21 O4i129; symmetry code: (i) 1ÿx, yÿ1
2, 12ÿz] into zigzag molecular chains along thebdirection (Fig. 2). These interactions, along with the dipole±dipole and van der Waals interactions, stabilize the packing.
Experimental
The title compound was prepared by photoinduced oxygenation of 1,3-dibenzoyl-2-phenylindolizine in acetonitrile and was isolated by column chromatography. Single crystals for X-ray measurement were obtained by slow evaporation of the solvent from a petroleum ether± ethyl acetate (5:1v/v) solution.

S1. Comment
Photoinduced oxygenation reactions of indolizine derivatives have been investigated intensively in our previous study
(Tian et al., 2001). In continuation of that work, we have isolated the title compound, (I), which was obtained from the
photo-oxygenation reactions of 1,3-dibenzoyl-2-phenylindolizine. We report here an X-ray crystallographic analysis at
213 K of (I), which was undertaken to establish its conformation and stereochemistry.
The bond lengths and angles observed in (I) (Fig. 1) are within normal ranges (Allen et al., 1987). The values within the
oxirane (O3/C9/C16) agree with those of a related structure studied previously (Krishnakumar et al., 2002), except for a
slight elongation of the C9—C16 bond [1.509 (3) Å versus 1.488 (4) Å (Krishnakumar et al., 2002)] due to the bulky
substituents attached at atoms C9 and C16. The configurations of the substituents are conditioned by these two Csp3
atoms. Except for the bond angles within the oxirane, the average bond angles subtended at atoms C9 and C16 are 117.2
and 116.8°, respectively, while the two atoms are eclipsed, as determined by the torsion angles C8—C9—C16—C17 =
1.4 (3)° and C10—C9—C16—C22 = 4.7 (3)°.
In the dioxophenylethylene moiety (O1/O2/C1–C9), the two carbonyl groups form O1/C6/C7/C8 and O2/C7/C8/C9
planes. These two planes are twisted out of the phenyl ring by 11.7 (1) and 38.8 (1)°, respectively. The O2/C7/C8/C9
plane and the C10–C15 phenyl ring attached at atom C9 form dihedral angles of 56.1 (1) and 63.6 (2)°, respectivley, with
the oxirane ring plane.
The pyridine ring (N1/C17–C21) attached at atom C16 is perpendicular to the oxirane ring plane, with a dihedral angle
of 88.6 (2)°. The carbonyl group of the benzoyl moiety (O4/C22–C28) attached at the same atom is twisted from its
aromatic ring by an angle of 20.8 (1)° and the O4/C16/C22/C23 plane makes a dihedral angle of 61.8 (2)° with the
oxirane ring plane.
In the packing, the molecules are interconnected by C21—H21···O4i interactions [H21···O4i 2.56 Å and C21—H21···O4i
129°; symmetry code: (i) 1 − x, y − 1/2, 1/2 − z] into zig-ag molecular chains along the b direction (Fig. 2). These
interactions, along with the dipole–dipole and van der Waals interactions, stabilize the packing.

Special details
Experimental. The data collection covered over a hemisphere of reciprocal space by a combination of three sets of exposures; each set had a different φ angle (0, 88 and 180°) for the crystal and each exposure of 10 s covered 0.3° in ω. The crystal-to-detector distance was 4 cm and the detector swing angle was −35°. Crystal decay was monitored by repeating fifty initial frames at the end of data collection and analysing the intensity of duplicate reflections, and was found to be negligible.
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes.
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2,
conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used
only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2
