4-(4-Methoxyphenyl)-2-oxo-1,2,5,6-tetrahydrobenzo[h]quinoline-3-carbonitrile
In the molecule of the title compound, C(21)H(16)N(2)O(2), the tetrahydrobenzo[h]quinoline fused-ring system is buckled owing to the ethylene –CH(2)CH(2)– 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 r...

| description | In the molecule of the title compound, C(21)H(16)N(2)O(2), the tetrahydrobenzo[h]quinoline fused-ring system is buckled owing to the ethylene –CH(2)CH(2)– 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 50.3 (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. |
