Abstract
In the title compound, C15H11BrN4OS, the least-squares plane through the 5-bromo-isatin fragment forms a dihedral angle of 13.63 (14)° with the phenyl ring. The mol-ecular conformation features intra-molecular N-H⋯N and N-H⋯O hydrogen bonds. In the crystal, mol-ecules are connected via pairs of N-H⋯O inter-actions into centrosymmetric dimers. Additionally, π-π stacking inter-actions link mol-ecules into chains parallel to the a axis with short C⋯C distances being observed between the phenyl and thio-carbonyl [3.236 (8) Å] groups and between the thio-carbonyl and carbonyl [3.351 (4) Å] groups of stacked mol-ecules.Entities:

| Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
