2-Meth­oxy-4-(2-meth­oxy­phen­yl)-5,6,7,8,9,10-hexa­hydro­cyclo­octa­[b]pyridine-3-carbo­nitrile

In the title compound, C₂₀H₂₂N₂O₂, the central pyridine ring forms a dihedral angle of 76.32 (8)° with the pseudo-axial benzene ring. The cyclo­octane ring adopts a twisted boat chair conformation. In the crystal, weak inter­molecular C—H...π inter­actions between inversion-related mol­ecules result in the formation of linear double chains along the b-axis direction.

4-(2-Fluoro­phen­yl)-2-meth­oxy-5,6,7,8,9,10-hexa­hydro­cyclo­octa­[b]pyridine-3-carbo­nitrile

In the title compound, C₁₉H₁₉FN₂O, the cyclo­octene ring adopts a twisted boat-chair conformation. The dihedral angle between the plane of the fluorophenyl substituent and that of the pyridine ring is 76.39 (8)°. The F and ortho-H atoms of the fluoro­benzene ring are disordered, with occupancy factors of 0.226 (5) and 0.774 (5). In the crystal, no significant inter­actions are observed between the mol­ecules beyond van der Waals contacts.
