Abstract: The title compound, C13H11N3S, crystallizes with two independent molecules in the asymmetric unit. The two molecules are geometrically very similar and differ mainly in a spatial orientation of the benzene and thieno[3,2-d]pyrimidine ring systems [dihedral angles = 69.49 (4) and 79.05 (3)°]. The nine-membered thieno[3,2-d]pyrimidine moieties have a planar conformation (r.m.s. deviations = 0.020 and 0.012 Å). In the crystal, molecules are linked through N-HN, N-HC and C-H non-covalent contacts into chains along the c axis, while neighbouring chains are connected via C-HN interactions.
