N '-[(2Z)-3-Allyl-4-Oxo-1,3-Thiazolidin-2-ylidene]-5-Fluoro-3-Phenyl-1H-Indole-2-Carbohydrazide

Abstract

In the title compound, C<inf>21</inf>H<inf>17</inf>FN<inf>4</inf>O <inf>2</inf>S, 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 dihydro-thia-zolyl ring. The -CH2CH=CH2 substituent is disordered over two positions in a 0.51 (1):0.49 (1) ratio. An intra-molecular N - H⋯S hydrogen bond generates an S(5) ring motif. The two independent mol-ecules are linked into a dimer by two N - H⋯O hydrogen bonds, forming an R<inf>2</inf> 2(10) ring motif. The crystal structure features inter-molecular C - H⋯π and π-π stacking [centroid-centroid distance = 3.679 (1) Å] inter-actions. C - H⋯O and C - H⋯F inter-actions are also present.
