Abstract: The asymmetric unit of the title compound, C19H12ClN3O, 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...[pi] interactions and Cl...Cl contacts [Cl...Cl = 3.3896 (14) Å].
