The molecule of the title compound, C20H16N2O2, is centrosymmetric, the inversion center being located Fragrances at the mid-point of the central azine bond.The conformation around the C=N bond is E.The whole molecule (except for the H atoms) is essentially planar, with an r.
m.s.deviation of 0.
07 Å.In the crystal, Coffee Tables molecules are linked head-to-tail by pairs of C—H.O hydrogen bonds, forming inversion dimers, and resulting in the formation of chains propagating along [011].
