Ethyl 2-[(Z)-2-(2-nitrophenyl)hydrazinylidene]propanoate

Abstract

In the molecule of the title compound, C11H13N3O4, all non-H atoms are nearly coplanar with the largest deviation from the mean plane being 0.152 (2) Å. A strong intramolecular N—H...O hydrogen bond closes a six-membered ring. In the crystal, molecules are linked by π–π interactions [intercentroid distance = 3.724 (2) Å], forming stacks parallel to thecaxis.
