(1R*2S*)-2-Nitro-1-(4-nitro­phen­yl)propanol

摘要

The title compound, C9H10N2O5, presents a racemic mixture of two enanti­omeric diastereomers. In the crystal, mol­ecules assemble into zigzag chains parallel to the b axis [C(6) motif] due to the formation of elongated O—H⋯O(N) hydrogen bonds. Of inter­est is the fact that only the aliphatic nitro group is involved in hydrogen bonding and it adopts a gauche conformation with respect to the OH group.
