(RS)-1-(1-Acetylindolin-5-yl)-2-chloropropan-1-one

Abstract

The molecule of the title compound, C13H14ClNO2, is roughly planar [maximum deviation = 0.060 (2) Å] with the disordered Cl/CH3 group asymetrically distributed on both sides of the mean plane. Indeed, the Cl and CH3 located on the stereogenic carbon exchange each other with occupancy factors in the ratio 0.60:0.40. The whole crystal is a racemate. Non-classical C—H...O hydrogen bonds and π–π interactions [centroid–centroid distance = 3.6959 (9) Å] between symmetry-related phenyl rings stabilize the crystal structure.
