2-Amino-4-(4-chloro­phen­yl)-5-oxo-5,6,7,8-tetra­hydro-4H-chromene-3-carbonitrile

In the title moleclue, C16H13ClN2O2, the cyclo­hexene ring is in a sofa conformation. The pyran ring is essentialy planar [maximum deviation = 0.038 (2) Å] and forms a dihedral angle of 89.68 (10)° with the benzene ring. In the crystal, mol­ecules are linked by pairs of N-H...N hydrogen bonds, forming inversion dimers with R22(12) ring motifs. These dimers are further linked by N-H...O hydrogen bonds into chains along [110]. Weak C-H...O hydrogen bonds are also present.
