Description
Summary:In the molecule of the title compound, C20H14N2O, the tetrahydrobenzo[h]quinoline fused-ring system is buckled owing to the ethylene –CH2CH2– fragment, the benzene ring and the pyridine ring being twisted by 19.7 (1)°. The 4-substituted aromatic ring is bent away from the pyridine ring by 62.9 (1)° in order to avoid crowding the cyanide substituent. In the crystal, two molecules are linked by a pair of N—H...O hydrogen bonds to form a centrosymmetric dimer.
