Abstract: | In the title compound, C17H10F6N4O2S, an intramolecular N— H N hydrogen bonds forms an S(5) ring whereas N—H O and C—H S interactions 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 molecules are dimerized due to N—H O interactions. – interactions are present between the benzene rings [centroid–centroid distance = 3.6913 (15) A˚ ] and between the five membered ring and the trifluoromethyl)phenyl ring [centroids–centroid distance = 3.7827 (16) A˚ ]. One of the trifluoromethoxy F atoms is disordered over two sites with occupancy ratio of 0.76 (3):0.24 (3). The F atoms of the p-trifluoromethyl substituent are disordered over three sets of sites with an occupancy ratio of 0.70 (2):0.152 (11):0.147 (13) |
