2-[(E)-(Dimethylamino)methyleneamino]-N-phenylbenzenesulfonamide

Abstract

Key indicators: single-crystal X-ray study; T = 153 K; mean (C-C) = 0.002 Å; R factor = 0.032; wR factor = 0.082; data-to-parameter ratio = 13.2.In the title compound, C 15 H 17 N 3 O 2 S, all bond lengths and angles are normal. Intramolecular N-HÁ Á ÁN hydrogen bonding influences the molecular conformation. The benzene and phenyl rings make a dihedral angle of 75.80 (2) . In the crystal structure, weak intermolecular C-HÁ Á ÁO hydrogen bonds link the molecules into zigzag chains extended along the b axis.
