4,4′,6,6′-Tetra-tert-butyl-2,2′-[1,2-phenylenebis(nitrilomethylidyne)]diphenol acetone solvate

In the Schiff base molecule of the title compound, C36H48N2O2·C3H6O, the central benzene ring makes dihedral angles of 46.64 (10) and 49.34 (10)° with the two outer benzene rings, and the two outer benzene rings form an angle of 39.13 (8)°. There are two intramolecular O—H⋯N hydrogen bonds involving the two hydroxy groups, which generate S(6) ring motifs. In the crystal structure, the Schiff base molecules are linked into a chain along the a axis by C—H⋯π interactions. The acetone solvent molecules are attached to the chain via C—H⋯O hydrogen bonds.
