Abstract The title compound (C9H12N2O5,M r =228.2) crystallizes in the trigonal space groupP31,21 witha=b=9.438(3) andc=19.775(3) Å,V=1525.5 Å3,D x =1.490 gm cm−3,Z=6,μ=0.12 mm−1,F(000)=720.0,T=293 K. The structure was solved by direct methods and refined by full-matrix least-squares calculations to anR value of 0.044 on 843 unique observed reflections. The dioxane ring adopts a chair conformation. The crystal structure is stabilized by N-H⋯O hydrogen bonds and C-H⋯O close contacts.
