Abstract

The title compound, C17H16N2O5S2, adopts a transoidcisoid disordered crystal structure of the terminal thienyl group at room temperature, with occupancies of 0.55 and 0.45. The structure was solved by direct methods and refined by least-squares calculations to a final R of 0.048. Molecular cohesion is stabilized by hydrogen bonding involving the two hydroxyl groups of the sugar moiety and the uridine ring.
