چکیده
The whole mol-ecule of the title compound, C32H34N2O2, is generated by inversion symmetry; the central benzene ring being situated about the crystallographic inversion center. The aromatic ring of the julolidine moiety is inclined to the central benzene ring by 33.70 (12)°. There are two intra-molecular O-H⋯N hydrogen bonds in the mol-ecule, generating S(6) ring motifs. The conformation about the C=N bonds is E. The fused non-aromatic rings of the julolidine moiety adopt half-chair conformations. In the crystal, adjacent mol-ecules are linked by pairs of C-H⋯π inter-actions, forming a ladder-like structure propagating along the a-axis direction.
