Abstract: The title compound, C₁₄H₁₆N₂, adopts a trans-planar conformation. However, the molecule, which possesses C_i point group symmetry, crystallizes in the non-centrosymmetric space group P2₁2₁2₁. In the crystal structure, the molecular symmetry is only approximately retained. The crystal packing is predominantly stabilized by N-HN hydrogen bonds. Weak C-H interactions also contribute to the stability.
