Abstract

The asymmetric unit of the title compound, C30H28N2O2, comprises half of a potential tetra­dentate Schiff base ligand; an inversion centre is situtated at the center of the butane­diamine spacer. The central methyl­ene segment of the diamine spacer is disordered over two positions with a refined site-occupancy ratio of 0.651 (7):0.349 (7). The phenyl ring and the hy­droxy-substituted benzene ring are almost perpendicular to each other, with a dihedral angle of 87.90 (8) Å. Intra­molecular O—H⋯N hydrogen bonds make S(6) ring motifs.
