N'-[(2Z)-3-Allyl-4-oxo-1,3-thia-zolidin-2-yl-idene]-5-fluoro-3-phenyl-1H-indole-2-carbohydrazide.

Abstract

In the title compound, C21H17FN4O2S, the planar indole fused-ring [maximum deviation 0.009 (1) Å] makes dihedral angles of 54.75 (9) and 14.90 (9)°, respectively, with the phenyl ring and the dihydro­thia­zolyl ring. The –CH2CH=CH2 substituent is disordered over two positions in a 0.51 (1):0.49 (1) ratio. An intra­molecular N—H⋯S hydrogen bond generates an S(5) ring motif. The two independent mol­ecules are linked into a dimer by two N—H⋯O hydrogen bonds, forming an R 2 2(10) ring motif. The crystal structure features inter­molecular C—H⋯π and π–π stacking [centroid–centroid distance = 3.679 (1) Å] inter­actions. C—H⋯O and C—H⋯F inter­actions are also present.
