2-Amino-4-(4-chloro-phen-yl)-4H-chromeno[8,7-b]pyridine-3-carbonitrile.

ABSTRACT: The asymmetric unit of the title compound, C19H12ClN3O, contains two mol-ecules 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 mol-ecules) and the main difference between them is seen in the twist about the bond linking the main residue to the attached chloro-benzene rings [dihedral angles = 79.01?(12) and 76.22?(11)° for the two mol-ecules]. Zigzag supra-molecular 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?? inter-actions and Cl?Cl contacts [Cl?Cl = 3.3896?(14)?Å].
