Abstract: The crystal structure of the title compound, C₁₈H₁₆ClN₃O₃, was determined because of its biological and pharmaceutical properties. In the molecule, the spiro junction links a planar oxindole ring and a pyrrolidine ring. The pyrrolodine ring is in an envelope conformation. The methyl, nitro and chlorophenyl groups are equatorial with respect to the pyrrolidine ring. A centrosymmetric dimer is formed via N-HO intermolecular hydrogen bonds. C-HO and C-HCl intermolecular hydrogen bonds stabilize the molecules in the crystal structure. A couple of weak C-H intermolecular interactions are also observed.
