Tóm tắt The title compound, C9H8N2O2S3, crystallizes with two mol­ecules (A and B) in the asymmetric unit. Both have similar conformations (overlay r.m.s. deviation = 0.209 Å) and are linked by an N—H⋯O hydrogen bond. In both mol­ecules, the thio­phene rings show orientational disorder, with occupancy factors of 0.6727 (17) and 0.3273 (17) for mol­ecule A, and 0.7916 (19) and 0.2084 (19) for mol­ecule B. The five-membered rings make an angle of 79.7 (2)° in mol­ecule A and an angle of 66.8 (2)° in mol­ecule B. In the crystal, chains of mol­ecules running along the a-axis direction are linked by N—H⋯O hydrogen bonds. The inter­action of adjacent chains through N—H⋯O hydrogen bonds leads to two types of ring structures containing four mol­ecules and described by the graph-set motifs R 4 4(18) and R 4 2(14).
