4-Azido­methyl-7-methyl-2-oxo-2H-chromene-6-sulfonyl azide

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 methyl­ene 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 inter­actions, 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.
