title: 4-[(E)-2-(2,4,6-Trinitro-phenyl)ethyl-idene]benzonitrile.
abstract: In the crystal of the title compound, C(15)H(8)N(4)O(6), the mol-ecules are organized in layers due to their linkage by weak C-H⋯N hydrogen bonds. The layers are themselves inter-connected by weak C-H⋯O hydrogen bonds and π-π inter-actions [centroid-centroid distances = 3.8690 (15) and 3.9017 (16) Å]. The dihedral angle between the rings is 31.9 (1)°.
