Azinyl sulfides. LXXXI. 14-Phenyl-7-thiapyrano2,3-c;6,5-c 'diquinoline-14-carbonitrile

In English The molecules of the title compound, C26H15N3S, have a pentacyclic ring system which is almost planar, with the central ring in a flattened boat conformation. The folding angle between the two quinoline rings is 6.75 ( 7)degrees. The 14- phenyl substituent is in a quasi- axial conformation, while the 14-cyano substituent is in a quasi- equatorial conformation with respect to the thiopyran ring. The S center dot center dot center dot C - C-phenyl and S center dot center dot center dot C - C-CN angles are 116.8 ( 2) and 129.3 ( 2) degrees, respectively. The plane of the phenyl group is nearly coplanar with the plane bisecting the dihedral angle of the pentacyclic ring system.
