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

In the title compound, C(14)H(11)N(3)O(3), 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 R (2) (2)(8) loops. The dimers are linked by C—H⋯N and...

Descripción
Sumario:In the title compound, C(14)H(11)N(3)O(3), 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 R (2) (2)(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.
