Abstract: The salicylideneaniline moiety in the centrosymmetric title compound, C₂₈H₂₄N₂O₂, is a phenol-imine tautomer which is non-planar and photochromic. A strong intramolecular hydrogen-bonding interaction, which is a common feature in related imine-phenol compounds, stabilizes the molecular structure. The system in the salicylideneaniline moiety interacts with symmetry-related systems through face-to-face - interactions and C-H interactions, to stabilize the molecules in the crystal structure.
