1,3,5-Trinitro-2,4-bis(2-phenylethenyl)benzene

In the title compound, C(22)H(15)N(3)O(6), the central benzene ring and one of the phenyl rings are essentially parallel to each other, making a dihedral angle of 1.35 (16)degrees. The dihedral angle between the two phenyl rings is 83.56 (19) degrees. Intramolecular C-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds occur. In the crystal, molecules are linked through C-H center dot center dot center dot O hydrogen bonds. Furthermore, offset face-to-face pi-pi interactions with centroid-centroid distances of 3.644 (2) angstrom help to stabilize the crystal structure.
