title: 1-[2-Oxo-5-(trifluoro-meth-oxy)indolin-3-yl-idene]-4-[4-(trifluoro-methyl)-phen-yl]thio-semicarbazide.
abstract: In the title compound, C(17)H(10)F(6)N(4)O(2)S, an intra-molecular N-H⋯N hydrogen bonds forms an S(5) ring whereas N-H⋯O and C-H⋯S inter-actions complete S(6) ring motifs. The dihedral angle between the fused ring system and the phenyl ring is 6.68 (8)°. In the crystal, the mol-ecules are dimerized due to N-H⋯O inter-actions. π-π inter-actions are present between the benzene rings [centroid-centroid distance = 3.6913 (15) Å] and between the five membered ring and the trifluoro-meth-yl)phenyl ring [centroids-centroid distance = 3.7827 (16) Å]. One of the trifluoro-meth-oxy F atoms is disordered over two sites with occupancy ratio of 0.76 (3):0.24 (3). The F atoms of the p-trifluoro-methyl substituent are disordered over three sets of sites with an occupancy ratio of 0.70 (2):0.152 (11):0.147 (13).
