Crystal and molecular structure of 6-exo-methyl-6-endo-nitro-2-exo-phenylbicyclo[2.2.1]heptan-2-endo-ol

The molecular and crystal structure of the title compound2, prepared in racemic form by addition of phenylmagnesium bromide to 6-exo-methyl-6-endo-nitrobicyclo[2.2.1]heptan-2-one (1) in the presence of cerium(III) chloride, were determined by single-crystal X-ray diffraction. The crystal selected for analysis was found to belong to the chiral orthorhombic space group P2₁2₁2₁, witha=6.685(3),b=10.0788(5),c=18.581(1) Å. In the crystal, molecules of2 are associated by intermolecular hydrogen bonds between hydroxy and nitro groups (OH...O₂N=0.82 Å).Nitrobicyclo[2. 2. 1]heptanes. Part 10. Part 9: Michael, Maqutu and Denner (1991).
