摘要
In the title compound, C14H9FN2O2S, the thieno[2,3-b] pyridine residue is almost planar (r.m.s. deviation = 0.0194 angstrom), with the carboxylic acid group [dihedral angle = 11.9 (3)(circle)] and the benzene ring [71.1 (4)(circle)] being twisted out of this plane to different extents. An intramolecular N-H...O(carbonyl) hydrogen bond closes an S(6) ring. Supramolecular chains along [011] mediated by O-H...N(pyridine) hydrogen bonds feature in the crystal. A three-dimensional architecture is completed by pi-pi interactions occurring between the benzene ring and the two rings of the thieno[2,3-b] pyridine residue [centroid-centroid distances = 3.6963 (13) and 3.3812 (13) angstrom]. The F atom is disordered over the two meta sites in a near statistical ratio [0.545 (5): 0.455 (5)].
