Abstract

The title compound, C₃₈H₄₀N₂·0.375C₆H₁₄, crystallizes in the monoclinic space group P2₁/c and has a host-guest structure with the helicene molecules forming a porous structure and mol-ecules of hexane inserted into the holes. The dihedral angles between the two carbazole sections of the right- and left-handed helicenes are 27.44 (3) and 25.63 (3)°, respectively. There are no classical π-π inter-actions or hydrogen-bonding inter-actions present between adjacent mol-ecules in the crystal structure. The hexane solvent mol-ecule shows positional disorder.

Keywords: carbazole derivative; clathrate; crystal structure; helicene; π-conjugated.
