(a) Displacement ellipsoid plot (50% probability) of 2-oxo-2H-chromen-7-yl-tri­fluoro­methane­sulfonate, I, with complete atom labeling. (b) View of I along the edge of the coumarin plane. This perspective is from a position that is rotated by 90° from that shown in (a). Displacement ellipsoids are presented at the 50% probability level.
