title: 1-(2-Oxoindolin-3-yl-idene)-4-[2-(tri-fluoro-meth-yl)phen-yl]thio-semicarbazide.
abstract: In the title compound, C(16)H(11)F(3)N(4)OS, the dihedral angle between the aromatic ring systems is 69.15 (10)°. Intra-molecular N-H⋯N and N-H⋯O hydrogen bonds generate S(5) and S(6) rings, respectively. A short N-H⋯F contact also occurs. In the crystal, inversion dimers linked by pairs of N-H⋯O hydrogen bonds generate R(2) (2)(8) loops. The dimers are linked by N-H⋯F hydrogen bonds, forming polymeric chains propagating in [100]. π-π inter-actions also exist between the centroids of the benzene rings of the 2-oxoindoline group at a distance of 3.543 (3) Å and a short C=O⋯π contact occurs. Two F atoms of the trifluoro-methyl group are disordered over two sets of sites in a 0.517 (8):0.483 (8) ratio.
