Synthesis, crystal structure and Hirshfeld surface analysis of 1-(12-bromo-dodec-yl)indoline-2,3-dione.

In the title compound, CHBrNO, the indoline portion is almost planar and the 12-bromo-dodecyl chain adopts an all- conformation apart from the terminal C-C-C-Br fragment. A micellar-like structure is generated in the crystal by C-H⋯O hydrogen bonds and π-stacking inter-actions between indolinedione head groups and inter-calation of the 12-bromo-dodecyl tails. The Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (58.9%), H⋯O/O⋯H (17.9%) and H⋯Br/Br⋯H (9.5%) contacts. A density functional theory (DFT) optimized structure at the B3LYP/ 6-311 G(d,p) level shows good agreement with the experimentally determined mol-ecular structure in the solid state.
