Conformational preferences and supramolecular aggregation in 2-nitrophenylthiolates: 2-nitrophenyl-beta-D-thiogalactopyranoside
In the title compound, C(12)H(15)NO(7)S, the molecular conformation shows a concerted disrotatory twist of the nitro group and the galactose fragment out of the plane of the aryl ring. The molecules are linked by O-H.O hydrogen bonds [O.O range 2.725 (2)-3.024 (2) A and O-H.O range 155-175 degrees ] to form a three-dimensional framework.
