1-(5-Nitro-2-oxoindolin-3-ylidene)thiosemicarbazide

What is it about?

In the title molecule, C9H7N5O3S, there is an intramolecular N-H...O. The molecule is essentially planar, with the maximum deviation from the mean plane of the 18 non-H atoms being 0.135 (2) Å for the amine N atom. In the crystal, the molecules are connected via intermolecular N-H...O and N-H...S hydrogen bonds, forming two-dimensional networks lying parallel to (10\overline4). They are separated by an interplanar distance of 3.3214 (9) Å, leading to [pi]-[pi] interactions which stabilize the crystal structure.
