title: FF-beta-D-arabinofuranosyluracil.
abstract: In the title compound, 1-(2-deoxy-2-fluoro-beta-D-arabino-furanosyl)-5-fluoropyrimidine-2, 4(1H,3H)-dione, C9H10-F2N2O5, the furanosyl ring adopts the twisted conformation (T) with O1' endo and C1' exo. The crystal structure is characterized by a three-dimensional hydrogen-bond network involving the three H atoms bonded to heteroatoms.
