Crystal structure of 3,5-bis­(4-chloro­phen­yl)-1-propyl-1,3,5-tri­aza­cyclo­hexane

In the title mol­ecule, C₁₈H₂₁Cl₂N₃, the tri­aza­cyclo­hexane ring adopts a chair conformation with both 4-chloro­phenyl substituents in axial positions and the propyl group in an equatorial site. The dihedral angle between the planes of the benzene rings is 49.5 (1)°. In the crystal, mol­ecules are arranged in a head-to-tail fashion, forming columns along [010], and pairs of weak C—H...π inter­actions form inversion dimers between columns.
