In the title compound, 4- amino- 7-( 2- deoxy-beta-D-erythro- pentofuranosyl)-5- fluoro- 7H- pyrrolo[ 2,3- d] pyrimidine, C11H13FN4O3, the conformation of the glycosyl bond lies between anti and high anti [ chi = - 101.1 ( 3)degrees]. The furanose moiety adopts the S- type sugar pucker ( T-2(3)), with P = 164.7 ( 3)degrees and tau = 40.1 (2)degrees. The extended structure is a three- dimensional hydrogen- bond network involving a C - H center dot center dot center dot F, two N - H center dot center dot center dot O and two O - H center dot center dot center dot O hydrogen bonds.
