Of particular note is the occurrence of RC - H⋯N -=N+=NR interactions between an aromatic C - H group and an azide moiety which, in conjunction with a complementary C - H⋯O=C interaction, forms a nine-membered ring.engdata-to-parameter ratio = 16.0meanω(C - C) = 0.004 A °Rfactor = 0.050single-crystal X-ray studyT = 153 KwRfactor = 0.154Article
