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

What is it about?

In the title compound, C9H7FN4OS, 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.
