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

Abstract

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.
