Abstract: M r = 306.4, monoclinic, P21, a = 14.686 (6), b=5.359(4), c=9.439(3) A, fl=98.68(3) ° , V= 734.4 (7)/I,3, Z = 2, D x = 1.38 Mg m -3, 2(Mo Kct) = 0.7107 A, /t = 0-22 mm -1, F(000) = 324, T= 300 K, final R=0.042 (wR=0.037) for 1987 observed independent reflections. The sugar ring has a conformation intermediate between 3T 2 and 3E. The configuration of the imidazole ring with respect to the furanose ring is anti, the glycosidic angle being -9.3 (4) ° . The crystal packing is governed by hydrogen bonds involving OH groups and S atoms, forming infinite chains along [001].
