C-H...O and C-H...N inter­actions in three hexa­hydro­cyclo­octa­[b]pyridine-3-carbo­nitriles

R. Vishnupriya, J. Suresh, S. Maharani and R. R. Kumar

Synopsis: Three hexahydrocycloocta[b]pyridine-3-carbonitriles differing in the nature of the substituents either at the 2-position of the central pyridine ring or on the pendent aryl ring are presented, demonstrating that changes in the substituents cause significant differences in molecular conformation, intermolecular interactions and packing.

Formula: C20H22N2O2, C20H21N3O3 and C21H24N2O2
