In the mol-ecule of the title compound, C(18)H(12)N(2)OS, the tetra-hydro-benzo[h]quinoline fused-ring system is buckled owing to the ethyl-ene -CH(2)CH(2)- fragment, the benzene ring and the pyridine ring being twisted by 16.0 (1)°. The 4-substituted aromatic ring is bent away from the pyridine ring by 59.5 (2)° (for the major disordered thienyl component) in order to avoid crowding the cyanide substituent. In the crystal, two mol-ecules are linked by a pair of N-H⋯O hydrogen bonds to form a centrosymmetric dimer. The thienyl ring is disordered over two sites in a 72.7 (2):27.3 ratio.
在标题化合物C(18)H(12)N(2)OS的分子中，由于乙烯基-CH(2)CH(2)-片段，四氢苯并[h]喹啉稠环体系发生扭曲，苯环和吡啶环扭转了16.0 (1)°。4-取代的芳香环与吡啶环弯曲了59.5 (2)°（对于主要无序的噻吩基组分），以避免氰基取代基拥挤。在晶体中，两个分子通过一对N-H⋯O氢键相连形成一个中心对称的二聚体。噻吩环在两个位置上无序，比例为72.7 (2):27.3。
