The title compound, C17H11F5N4O, is described and compared with two closely related analogues in the literature. There are two independent molecules in the asymmetric unit, linked by N—H...O hydrogen bonds and π–π interactions into dimeric entities, presenting a noticeable noncrystallographicC2symmetry. These dimers are in turn linked by a medium-strength type-I C—F...F—C interaction into elongated tetramers. Much weaker C—H...F contacts link the tetramers into broad two-dimensional substructures parallel to (101).
