Crystal structure of 2-methyl-4-[(thio-phen-2-yl)methyl-idene]-1,3-oxazol-5(4H)-one.

ABSTRACT: 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 = 0.047 (1) and 0.090 (1) Å, respectively, for the S atoms] with the oxazole and thio-phene rings being inclined to one another by 2.65 (16)° in mol-ecule A and by 4.55 (15)° in mol-ecule B. In the crystal, the individual mol-ecules are linked via C-H⋯O hydrogen bonds, forming -A-B-A-B- chains along the [10-1] direction. The chains are linked via C-H⋯π and π-π inter-actions [inter-centroid distances = 3.767 (2) and 3.867 (2) Å] involving inversion-related oxazole and thio-phene rings in both mol-ecules, forming a three-dimensional structure.
