6,6′-Di-tert-butyl-2,2′-[1,2-phenyl­ene­bis(nitrilo­methyl­idyne)]diphenol

摘要

The mol­ecule of the title Schiff base compound, C28H32N2O2, has a twisted geometry, the dihedral angles between the central benzene ring and the other two benzene rings being 29.12 (14) and 26.01 (14)°. Four intra­molecular C—H⋯O hydrogen bonds and two intra­molecular O—H⋯N hydrogen bonds stabilize the mol­ecular structure. In the crystal packing, mol­ecules are stacked along the a axis and stabilized by π–π inter­actions [centroid–centroid distance = 3.6724 (17) Å]. The crystal studied was found to be a non-merohedral twin, the refined ratio of twin components being 0.374 (5):0.626 (5).
