Figure 2 Intra- and intermolecular contacts, viewed along [−1 0 0]. Green dashed lines indicate N—H⋯S hydrogen bonds, blue dashed lines N—H⋯O hydrogen bonds and purple dashed lines C—H⋯O contacts. Symmetry operators: i −x, y − , −z + ; ii −x, y + , −z + ; iii −x + 1, y − , −z − ; iv −x + 1, y + , −z − . |
