Abstract: The absolute configuration of the optically active title compound, (+)-3-chloro-1-(4-morpholino-5-nitroimidazol-1-yl)propan-2-ol, C₁₀H₁₅ClN₄O₄, has been confirmed as 2R by structure refinement using Friedel-pair reflections. The nitro group takes part in the conjugation system of the imidazole ring. In consequence, the exocyclic C-N bond is significantly shorter than the normal single Csp²-NO₂ bond. In the crystal structure, the molecules are linked by O-HN and C-HO intermolecular hydrogen bonds into an infinite three-dimensional network.
