Crystal structure of (Z)-2-(5-fluoro-2-oxoindolin-3-yl­idene)hydrazinecarbo­thio­amide

In the title compound, C(9)H(7)FN(4)OS, the mol­ecules are almost planar, with an r.m.s. deviation of 0.047 (3) Å from the mean plane defined by the non-H atoms and a maximum deviation of 0.123 (2) Å for the amine N atom. The torsion angle for the N—N—C—S unit is 176.57 (19)°. In the crystal, mol­ecules are linked into inversion dimers via pairs of N—H⋯F hydrogen bonds and, additionally, through N—H⋯O and N—H⋯S hydrogen bonds, building a two-dimensional hydrogen-bond network parallel to the (103) plane. An intra­molecular N—H⋯O inter­action is also observed.
