Abstract
2,4-Dichloro-N-[2,3-dihydro-4-(2,5-dimethoxyphenyl)thiazol-2-ylidene]benzenesulfonamide, C 17 H 14 Cl 2 N 2 O 4 S 2 , crystallizes in space group P1 with two independent molecules. The structural parameters do not indicate a tautomeric equilibrium but a single imino form. The main differences between the two crystalline forms lie in the intramolecular hydrogen bonding and the relative orientation of the methoxy groups. Attractive intermolecular interactions occur and are responsible for the crystalline cohesion.
