4-(5-Chloro-2-methyl-phen-yl)-1-[2-oxo-5-(trifluoro-meth-oxy)indolin-3-yl-idene]thio-semicarbazide.

The asymmetric unit of the title compound, C(17)H(12)ClF(3)N(4)O(2)S, contains two mol-ecules, which differ in their planarity and hydrogen bonding. In one mol-ecule, the 2-oxoindolin (C(8)/N/O A), thio-semicarbazide (N(3)/C/S B) and 5-chloro-2-methyl-phenyl (C(7)/Cl C) units are planar with r.m.s. deviations of 0.0110, 0.0173 and 0.0259†à , respectively. The dihedral angles A/B, B/C and A/C are 1.74†(15), 40.70†(13) and 41.00†(11)°, respectively. In the other mol-ecule the deviations are 0.0455, 0.0007 and 0.0143†à , respectively, and the dihedral angles are 5.01†(14), 4.53†(16) and 3.38†(13)°, respectively. In both mol-ecules, intra-molecular N-H⋯N and N-H⋯O hydrogen bonds form S(5) and S(6) ring motifs, respectively and C-H⋯S interactions occur. In one of the molecules, an intramolecular C-H⋯F interaction is also present. In the crystal, the mol-ecules are linked by N-H⋯O, C-H⋯F, C-H⋯O and N-H⋯S hydrogen bonding, forming a polymeric network.
