Crystal structure, DFT study and Hirshfeld surface analysis of 1-nonyl-2,3-dihydro-1H-indole-2,3-dione

In the title mol­ecule, C17H23NO2, the di­hydro­indole portion is planar (r.m.s. deviation = 0.0157 A) and the nonyl substituent is in an `extended' conformation. In the crystal, the nonyl chains inter­calate and the di­hydro­indole­dione units are associated through C—H⋯O hydrogen bonds to form micellar blocks. Based on the Hirshfeld surface analysis, the most important inter­molecular inter­action is the H⋯H inter­action.
