4-(5-Chloro-2-methyl­phen­yl)-1-[2-oxo-5-(trifluoro­meth­oxy)indolin-3-yl­idene]thio­semicarbazide

The asymmetric unit of the title compound, C(17)H(12)ClF(3)N(4)O(2)S, contains two mol­ecules, which differ in their planarity and hydrogen bonding. In one mol­ecule, the 2-oxoindolin (C(8)/N/O A), thio­semicarbazide (N(3)/C/S B) and 5-chloro-2-methyl­phenyl (C(7)/Cl C) units are planar with r.m.s. deviations of 0.0110, 0.0173 and 0.0259 Å, 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 mol­ecule the deviations are 0.0455, 0.0007 and 0.0143 Å, respectively, and the dihedral angles are 5.01 (14), 4.53 (16) and 3.38 (13)°, respectively. In both mol­ecules, intra­molecular 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 mol­ecules are linked by N—H⋯O, C—H⋯F, C—H⋯O and N—H⋯S hydrogen bonding, forming a polymeric network.
