Crystal structure and Hirshfeld surface analysis of N,N′-bis­(3-tert-butyl-2-hy­droxy-5-methyl­benzyl­idene)ethane-1,2-di­amine

The title compound, C(26)H(36)N(2)O(2), crystallizes in the phenol–imine form. In the mol­ecule, there are intra­molecular O—H⋯N hydrogen bonds forming S(6) ring motifs, and the two aromatic rings are inclined to each other by 37.9 (7)°. In the crystal, mol­ecules are linked by pairs of weak C—H⋯O hydrogen bonds, forming inversion dimers. Hirshfeld surface analysis and two-dimensional fingerprint plots indicate that the most important contributions to the crystal packing are from H⋯H (77.5%), H⋯C/C⋯H (16%), H⋯O/O⋯H (3.1%) and H⋯N/N⋯H (1.7%) inter­actions.
