The compound 3'-[(4-fluorophenyl)carbonyl]-5'-[2-(methylsulfanyl)ethyl]4'-(phenyl) spiro[indole-3,2'-pyrrolidin]-2(1H)-one, C30H31FN3O3S, crystallizes in the orthorhombic space group P212121 with unit cell parameters, a = 6.3529(8) Å, b = 11.4335(14) Å, c = 38.405(4) Å, α = β = γ = 90.0o, Z=4. The crystal structure was solved by direct methods. The data were collected at room temperature (293 K) and the structure was refined by full-matrix least-squares procedures to a final R-value of 0.1015 for 3630 observed reflections. The molecular structure is stabilized by one intra [C-H?O] and one DMF-guided inter [N-H?O] molecular interaction. Besides this, few CH∙∙∙π interactions have also been observed
