Abstract The title complex (C6H5NO3·C5H4N2O3,M r =279.21) crystallizes in the orthorhombic space groupPna21 witha=18.862(2),b=5.876(1),c=10.803(2) Å,V=1197.3(6) Å3,D c =1.549 g cm−3 forZ=4,F(000)=576, λ(MoKα)=0.71073 Å,μ=0.84 mm−1,T=297 K. The structure was solved by direct methods and refined by block matrix least-squares. FinalR=0.032, wR=0.037 for 904 observed reflections. The complex is held together by an intermediate hydrogen bond between the hydroxyl and the N-oxide group with an O⋯O distance equal to 2.618(3) Å. The stacking of thea glide related complex molecules by translation in theb direction results in a herringbone structure with an overlap of the nitrophenol and 4-nitropyridine N-oxide rings and a mean interplanar distance of 3.4(1) Å between those rings.
