Crystal structure of 4-azido-methyl-6-tert-butyl-2H-chromen-2-one.

In the title compound, C14H15N3O2, one of the methyl C atoms of the tert-butyl group lies almost in the plane of the chromene ring system [deviation = -0.097 (2) Å], one lies above and one lies below [deviations = 1.460 (3) and 1.006 (3) Å, respectively]. The C-C-N-N torsion angle is 142.33 (17)°. In the crystal, moelcules are linked by weak C-H⋯O hydrogen bonds to generate C(6) chains propagating in the [010] direction.
