2-[2-(2,4-Dinitro-phen-yl)eth-yl]-1,3,5-trinitro-benzene.

In the title compound, C(14)H(9)N(5)O(10), the two benzene rings are inclined at a dihedral angle of 14.81†(5)°, and the nitro groups are twisted with respect to the benzene rings to which they are attached, making dihedral angles of 57.89†(7), 14.93†(7), 62.58†(7), 2.80†(12) and 22.38†(12)°. Weak inter-molecular C-H⋯O hydrogen bonding is present in the crystal structure.
