Methyl 2-(5-chloro-1-methyl-2-oxo-2,3-dihydro-1H-indol-3-ylidene)acetate

Abstract

The title compound, C12H10ClNO3, the indoline ring system is essentially planar, with a maximum deviation of 0.009 Å for the N atom. The indoline ring and acetate group are essentially coplanar, with a maximum deviation of 0.086 Å for the O atom. The mean plane through the methoxycarbonylmethyl group forms a dihedral angle of 3.68 (5)° with the plane of the indoline ring system. The molecular structure is stabilized by an intramolecular C—H...O hydrogen-bond interaction. In the crystal, π–π stacking interactions [centroid–centroid distance = 3.7677 (8) Å] occur between benzene rings, forming a chain running along the c-axis direction.
