title: (3Z)-3-Hydrazinylideneindolin-2-one.
abstract: The title mol-ecule, C(8)H(7)N(3)O, is almost planar, with a maximum deviation of 0.0232 (2) Å from the least-squares plane. The Z conformation of the C=N double bond is stabilized by an intra-molecular N-H⋯O hydrogen bond. In the crystal, adjacent mol-ecules are linked by inter-molecular N-H⋯N and N-H⋯O hydrogen bonds, forming zigzag sheets parallel to the c axis; the sheets are further stabilized by π-π inter-actions [centroid-centroid distance = 3.7390 (10) Å].
