2-Amino-4-(4-chloro­phen­yl)-4H-chromeno[8,7-b]pyridine-3-carbonitrile

The asymmetric unit of the title compound, C(19)H(12)ClN(3)O, contains two mol­ecules with similar conformations. The 14 non-H atoms comprising the 4H-chromeno[8,7-b]pyridine residue are essentially coplanar (r.m.s. deviations = 0.037 and 0.042 Å for the two mol­ecules) and the main difference between them is seen in the twist about the bond linking the main residue to the attached chloro­benzene rings [dihedral angles = 79.01 (12) and 76.22 (11)° for the two mol­ecules]. Zigzag supra­molecular chains along the a-axis direction mediated by amino–pyridine N—H⋯N hydrogen bonds feature in the crystal packing; these are connected into a three-dimensional architecture by C—H⋯π inter­actions and Cl⋯Cl contacts [Cl⋯Cl = 3.3896 (14) Å].
