title: Crystal structure of 4-nitro-N-[(pyridin-2-yl)methyl-idene]aniline.
abstract: The title compound, C12H9N3O2, adopts an E conformation at the imine double bond. The pyridyl ring makes a dihedral angle of 47.78 (5)° with the benzene ring, indicating the mol-ecule is twisted. In the crystal, mol-ecules are π-π stacked into columns parallel to [100], with an inter-planar separation of 3.8537 (8) Å, corresponding to the length of the a axis. The chains are further linked via weak C-H⋯O and C-H⋯N hydrogen bonds, forming two-dimensional sheets parallel to (010). The sheets interact by van der Waals inter-actions.
