Crystal structure of 9,9′-{(1E,1′E)-[1,4-phenyl­enebis(aza­nylyl­­idene)]bis­­(methanylyl­­idene)}bis­­(2,3,6,7-tetra­hydro-1H,5H-pyrido[3,2,1-ij]quinolin-8-ol)

The whole mol­ecule 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 intra­molecular O—H⋯N hydrogen bonds in the mol­ecule, 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 mol­ecules are linked by pairs of C—H⋯π inter­actions, forming a ladder-like structure propagating along the a-axis direction.
