Abstract
In the title compound, C38H30N2O2, the acenaphthylene ring is close to being planar [maximum deviation = 0.1047 (11) angstrom]. The dihedral angles between the three benzene rings and the acenaphthylene system are 39.47 (3), 37.65 (3) and 44.47 (3)degrees. An intramolecular O-H center dot center dot center dot N interaction forms an S(5) hydrogen-bond ring motif. In the crystal, molecules are linked into [101] chains by a set of C-H center dot center dot center dot O interactions.
