Structure of 4-methyl-N-{2-[2-alkylamino-5-nitrophenyliminomethyl]phenyl}benzenesulfonamides

Structure of 4-methyl-N-{2-[2-alkylamino-5-nitrophenyliminomethyl]phenyl}benzenesulfonamides Abstract The structures of Schiff bases prepared by the condensation of 2-tosylaminobenzaldehyde with 2-alkylamino-5-nitroanilines were studied by X-ray diffraction. The intramolecular N-H…N hydrogen bonds result in the closure of six-membered hydrogen-bonded rings, which are either planar or nonplanar depending on the substituent. According to the results of quantum-chemical calculations, the distortion of the hydrogen-bonded ring is associated with the character of molecular packing in the crystal. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Crystallography Reports Springer Journals

Abstract

Abstract The structures of Schiff bases prepared by the condensation of 2-tosylaminobenzaldehyde with 2-alkylamino-5-nitroanilines were studied by X-ray diffraction. The intramolecular N-H…N hydrogen bonds result in the closure of six-membered hydrogen-bonded rings, which are either planar or nonplanar depending on the substituent. According to the results of quantum-chemical calculations, the distortion of the hydrogen-bonded ring is associated with the character of molecular packing in the crystal.
