Abstract: In the title compound, C14H14F3NO4, the 3,3,3-trifluoropyruvate fragment has a syn configuration and is noncoplanar with the indole plane [dihedral angle = 84.87 (5)°]. In the crystal, molecules form inversion-related dimers via pairs of intermolecular O-HO hydrogen bonds. These dimers are connected by intermolecular N-HO=C(CF3) hydrogen bonds to form a two-dimensional network structure.
