Conclusions
The E-molecular configuration of N2-benzenesulfonyl-N1-(3-nitrophenyl)benzamidine has been verified by x-ray structural investigation, which also made it possible to confirm the addition-elimination mechanism which had been proposed earlier for the reactions of N-aryl-sulfonylbenzimidoyl chlorides with aromatic amines in aprotic reaction media. Molecules of (II) are associated with one another in the crystal structure via H-bonds in a chain, while neighboring chains are associated with one another by means of the so-called “stacking” interactions.
