Crystal structure of 2-amino-7-hy­droxy-4-(4-hy­droxy­phen­yl)-4H-chromene-3-carbo­nitrile

In the title compound, C(16)H(12)N(2)O(3), the chromene ring system is nearly planar [maximum deviation from the mean plane = 0.057 (1) Å], and is almost perpendicular to the benzene ring, with a dihedral angle of 85.29 (5)°. In the crystal, mol­ecules are linked by classical N—H⋯O, O—H⋯O and O—H⋯N hydrogen bonds, and weak C—H⋯O hydrogen bonds, forming a three-dimensional supra­molecular network. Furthermore, a weak π–π stacking inter­action is observed; the centroid-to-centroid distance is 3.7260 (7) Å.
