Crystal structure, DFT and Hirshfeld surface analysis of 2-amino-4-(2-chloro­phen­yl)-7-hy­droxy-4H-benzo[1,2-b]pyran-3-carbo­nitrile

The benzo­pyran ring of the title com­pound, C(16)H(11)ClN(2)O(2), is planar [maximum deviation = 0.079 (2) Å] and is almost perpendicular to the chloro­phenyl ring [dihedral angle = 86.85 (6)°]. In the crystal, N—H⋯O, O—H⋯N, C—H⋯O and C—H⋯Cl hydrogen bonds form inter- and intra­molecular inter­actions. The DFT/B3LYP/6-311G(d,p) method was used to determine the HOMO–LUMO energy levels. The mol­ecular electrostatic potential surfaces were investigated by Hirshfeld surface analysis and two-dimensional fingerprint plots were used to analyse the inter­molecular inter­actions in the mol­ecule.
