摘要

The title compound, C20H27N3O, was synthesized by condensation reaction of 3,5-di-tert-butyl-4-hy­droxy­benzaldehyde and 2-hydrazinyl­pyridine, and crystallizes in the centrosymmetric monoclinic space group C2/c. The conformation about the C=N bond is E. The dihedral angle between the rings is 18.1 (3)°. An inter­molecular N—H⋯N hydrogen bond generates an R22(8) ring motif. In the crystal, N—H⋯N hydrogen bonds connect pairs of mol­ecules, forming dimers. Density functional theory (DFT) optimized structures at the B3LYP/6–311 G(d,p) level are compared with the experimentally determined mol­ecular structure in the solid state.
