In the title compound, C22H15N3O6, the central benzene ring and one of the phenyl rings are essentially parallel to each other, making a dihedral angle of 1.35 (16)°. The dihedral angle between the two phenyl rings is 83.56 (19)°. Intramolecular C—H⋯N and C—H⋯O hydrogen bonds occur. In the crystal, molecules are linked through C—H⋯O hydrogen bonds. Furthermore, offset face-to-face π–π interactions with centroid–centroid distances of 3.644 (2) Å help to stabilize the crystal structure.

The title compound was synthesized using 2,4,6-trinitro-m-xylene and benzaldehyde as the starting materials, according to the literature method (Peng et al., 1995). Single crystals suitable for X–ray diffraction were prepared by slow evaporation of a solution of the title compound in acetone at room temperature.

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 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Trinitrobenzene and its derivatives have been extensively reported for use as energetic materials (Ott & Benziger, 1987; Kuperman et al., 2006). The title compound may be useful as a high energy explosive (Peng et al., 1995), and here we present its crystal structure.
In the title compound (Fig. 1), the bond distances and bond angles are similar to those in 2,4,6-trintro-m-xylene (Bryden, 1972). The planes of two rings (C9—C14) and (C17—C22) are approximately parallel, with a dihedral angle of 1.35 (16)°. The two phenyl rings, (C1—C6) and (C17—C22), form a dihedral angle of 83.56 (19)°. The short distance of 3.644 (2) Å (symmetry code: -x,-y,1 - z) between the centroids of the two parallel rings (C9—C14) and (C17—C22) indicates the existence of offset face-to-face π-π interactions. Molecules are linked through C—H···O hydrogen bonds (Table 1), which help to stabilize the crystal structure. Intramolecular C—H···N and C—H···O hydrogen bonds are also present. There is a short intermolecular contact C15···C15 (1-x, -y, 1-z) of 3.185 (4) Å.
