In the title compound, C(11)H(8)N(6)O(4)S, the plane of the coumarin aromatic ring is twisted by 17.2 (2)° with respect to the plane of the azide group bound to the methyl-ene substituent, whereas it is twisted by 83.2 (2)° to the plane of the azide attached to the sulfonyl group. The crystal structure is stabilized by weak C-H⋯O inter-actions, leading to the formation of dimers with R(2) (2)(12) graph-set motifs. These dimers are further linked by weak S-O⋯π and π-π contacts [centroid-centroid distance = 3.765 (2) Å], leading to the formation of a layered structure.
