Abstract: The title mol-ecule, C7H7Cl2N 3OS, is approximately planar [maximum deviation = 0.062 (1) ]. Short inter-molecular distances between the centroids of the five-membered rings [3.5340 (8) ] indicate the existence of ?-? inter-actions. An inter-esting feature of the crystal structure is the presence of short intra-molecular Cl?N inter-actions [3.0015 (11) ]. Mol-ecules are linked via pairs of inter-molecular N - H?O hydrogen bonds, generating R 2 2(8) ring motifs. Furthermore, N - H?O hydrogen bonds form R 2 1(7) ring motifs with C - H?O contacts, further consolidating the crystal structure. In the crystal, mol-ecules are linked by these inter-molecular inter-actions, forming chains along [001]. 2009 Fun et al.
