(2Z)-3-(5-Hydroxy-4-oxo-4H-chromen-3-yl)acrylonitrile.
The title compound, C12H7NO3, consists of a chromone moiety substituted in position 3 with an acrylonitrile group in a Z configuration. The two planar groups are twisted with respect to one another. The only significant hydrogen bond in the structure is an intramolecular O-H...O bond. pi-pi contacts connecting aromatic groups and C-H...O intermolecular weak interactions lead to a supramolecular layer arrangement.
