N-[3-Cyano-2-oxo-5,6,7,8-tetrahydroquinoline-1(2H)-yl]-4-methylbenzenesulfonamide

Abstract

In the title compound, C17H17N3O3S, key bond lengths are N—N 1.408 (2) and N—S 1.7023 (15) Å. The relative orientation of the two ring systems is defined by the torsion angles between them, namely C—N—N—S 94.99 (15), N—N—S—C 123.90 (12) and N—S—C—C 107.86 (15)°. The mol­ecules are linked in inversion-symmetric pairs by classical hydrogen bonds N—H⋯O=C. All four CH2 groups of the non-aromatic ring are disordered over two positions, corresponding to two alternative conformations.
