Abstract: In the title compound, C11H9ClN2O, the fused-ring system is essentially planar, with a maximum deviation of 0.0323 (16) Å. In the crystal, molecules are connected by N-H
O hydrogen bonds forming a zigzag chain along the c axis. Molecules are further stacked along the a axis through weak
-
interactions, the shortest distance between ring centroids being 3.6476 (8) Å.
