RESUMO
The asymmetric unit of the title compound, C9H7NO2S, contains two crystallographically independent mol-ecules (A and B). Both mol-ecules are almost planar [maximum deviations = 0.047â (1) and 0.090â (1)â Å, respectively, for the S atoms] with the oxazole and thio-phene rings being inclined to one another by 2.65â (16)° in mol-ecule A and by 4.55â (15)° in mol-ecule B. In the crystal, the individual mol-ecules are linked via C-Hâ¯O hydrogen bonds, forming -A-B-A-B- chains along the [10-1] direction. The chains are linked via C-Hâ¯π and π-π inter-actions [inter-centroid distances = 3.767â (2) and 3.867â (2)â Å] involving inversion-related oxazole and thio-phene rings in both mol-ecules, forming a three-dimensional structure.
