Abstract
The crystal structure of the antitumor agent ino-N-(5-chloro-2-quinoxa linyl)benzenesulfonamide, C14H11ClN4O2S, has been determined by X-ray diffraction methods. The geometry around the S atom is distorted tetra hedral. The quinoxaline ring system is almost planar with a dihedral a ngle of 84.4 (2)degrees between the phenyl ring of the sulfonamide gro up and the quinoxaline ring. There is an intermolecular N-H O bond of 2.966 (6) Angstrom.
