Dimorphism and inclusion compounds of N,N'-di(benzenesulfonyl)-p-phenylenediamine

N. Nagel, H. Bock and P. Eller

Abstract: Crystal structures of a new polymorph of N,N'-(p-phenylene)bis(benzenesulfonamide) (C₁₈H₁₆N₂O₄S₂) and of two inclusion compounds with acetone [(CH₃)₂CO] and dimethylsulfoxide [2(CH₃)₂SO], respectively, have been determined at 150 K. For a more reliable comparison, the structure of the already known polymorph of N,N'-di(benzenesulfonyl)-p-phenylenediamine has been redetermined under identical conditions. In addition, the phase transformation behavior has been examined by differential scanning calorimetry and the crystallization conditions of both polymorphs including their formation by weathering of the inclusion compounds were investigated.
