Crystal structure of tris[4-(naphthalen-1-yl)phenyl]amine

In the title molecule, C₄₈H₃₃N, the central N atom shows no pyramidalization, so that the N atom and the three C atoms bound to the N atom lie almost in the same plane. The three para-phenylene rings bonded to the N atom are in a propeller form. All of the naphthalene ring systems are slightly bent. In the crystal, molecules form an inversion dimer, through two pairs of C-H…π interactions, which further interacts with the adjacent dimer via another two pairs of C-H…π interactions, forming a column structure along the a axis. There are no significant interactions between these column structures.
