摘要

The title compound, C9H8N2O2S3, crystallizes with two mol-ecules (A and B) in the asymmetric unit. Both have similar conformations (overlay r.m.s. deviation = 0.209??) and are linked by an N—H?O hydrogen bond. In both mol-ecules, the thio-phene rings show orientational disorder, with occupancy factors of 0.6727?(17) and 0.3273?(17) for mol-ecule A, and 0.7916?(19) and 0.2084?(19) for mol-ecule B. The five-membered rings make an angle of 79.7?(2)° in mol-ecule A and an angle of 66.8?(2)° in mol-ecule B. In the crystal, chains of mol-ecules running along the a-axis direction are linked by N—H?O hydrogen bonds. The inter-action of adjacent chains through N—H?O hydrogen bonds leads to two types of ring structures containing four mol-ecules and described by the graph-set motifs R44(18) and R42(14).
