Azinyl sulfides. LXXXI.(1)14-Phenyl-7-thiapyrano[2,3-c;6,5-c']diquinoline-14-carbonitrile

Abstract

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...C-C(phenyl) and S...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.
