2-(1H-Indol-3-yl)acetohydrazide

Abstract: In the title compound C10H11N3O, the mean plane of the indole ring system (r.m.s. deviation 0.0131 Å) subtends a dihedral angle of 87.27 (5)° to the almost planar acetohydrazide substituent (r.m.s. deviation 0.0291 Å). In the crystal, bifurcated N-H...(O,N) and N-H...N hydrogen bonds involving the pyrrole N-H grouping combine to form zigzag chains along a. Additional N-H...O contacts from the hydrazide N-H group augmented by C-H...[pi] interactions link the molecules into chains along the a axis. The overall effect of these contacts is a three-dimensional network structure with molecules stacked along the b-axis direction.
