Abstract
The title compound, C17H16N2O5S2, adopts a transoid-cisoid disordered crystal structure of the terminal thienyl group at room temperature, w ith occupancies of 0.55 and 0.45. The structure was solved by direct m ethods and refined by least-squares calculations to a final R of 0.048 . Molecular cohesion is stabilized by hydrogen bonding involving the t wo hydroxyl groups of the sugar moiety and the uridine ring.
