2-Cyano-N′-[(E)-1-(2-oxo-2H-chromen-3-yl)ethylidene]acetohydrazide

Abstract

In the title compound, C14H11N3O3, the chromene ring is almost planar, with a maximum deviation of 0.065 (2) Å from the mean plane for one of the C atoms. In the crystal, inversion dimers linked by pairs of N—H...O hydrogen bonds generate R22(8) loops. The dimers are linked by C—H...N and C—H...O interactions into a three-dimensional network. An aromatic π–π stacking interaction, with a centroid–centroid distance of 3.562 (10) Å, is also observed.
