Abstract

The preparation of the title compound, C26H25N, was achieved by the condensation of an ethano­lic mixture of benzaldehyde, cyclo­hexa­none and ammonium acetate in a 2:1:1 molar ratio. There are two crystallographically independent mol­ecules in the asymmetric unit. The two cyclo­hexyl rings adopt an anti-envelope conformation with the benzyl moiety adopting a cis conformation with respect to the nitro­gen atom of the phenanthridine segment. In the crystal, mol­ecules are linked through C—H⋯N inter­actions into hydrogen-bonded chains that are further arranged into distinct layers by weak offset π–π inter­actions.
