Abstract

In the title compound, C33H21NO3, the dihedral angle between the naphthalene units is 10.85 (4)° and the pyran ring adopts a shallow boat conformation. In the crystal, C-H· · ·N and C-H· · ·O hydrogen bonds link the molecules, enclosing R22(16) ring motifs. Hirshfeld surface analysis revealed that the most important contributions for the crystal packing are from H· · ·H, H· · ·C/C· · ·H, H· · ·O/ O· · ·H and C· · ·C interactions, at 45.8%, 27.3%, 11.2% and 9.6%, respectively.
