Methyl 2-[(Z)-5-bromo-2-oxoindolin-3-yl-idene]-hydrazinecarbodi-thio-ate

The title compound, C₁₀H₈BrN₃OS₂, a brominated di-thio-carbazate imine deriv-ative, was obtained from the condensation reaction of S-methyl-dithio-carbazate (SMDTC) and 5-bromo-isatin. The essentially planar mol-ecule exhibits a Z configuration, with the di-thio-carbazate and 5-bromo-isatin fragments located on the same sides of the C=N azomethine bond, which allows for the formation of an intra-molecular N-H⋯O_b (b = bromo-isatin) hydrogen bond generating an S(6) ring motif. In the crystal, adjacent mol-ecules are linked by pairs of N-H⋯O hydrogen bonds, forming dimers characterized by an R ² ₂(8) loop motif. In the extended structure, mol-ecules are linked into a three-dimensional network by C-H⋯S and C-H⋯Br hydrogen bonds, C-Br⋯S halogen bonds and aromatic π-π stacking.
