N-(3-Cyano-2-oxo-2,5,6,7,8,9-hexahydro-1H-cyclohepta[b]pyridin-1-yl)-4-methylbenzenesulfonamide

Abstract

The title compound, C18H19N3O3S, was identified as one of two possible isomers. Key bond lengths are N—N 1.402 (2) Å and N—S 1.6894 (18) Å. Classical hydrogen bonds N—H⋯O connect the mol­ecules to form inversion-symmetric dimers, which are further linked by a weak C—H⋯O hydrogen bond, forming ribbons.
