In the title compound, 4-amino-1-(2-deoxy-beta -D-erythro-pentofuranosyl)-1H-benzotriazole, C11H14N4O3, the conformation of the N-glycosidic bond is in the high-anti range [chi = - 77.1 (4)degrees] and the 2'-deoxyribofuranose moiety adopts a 2'-endo ( (2) E) sugar puckering. The 5'-hydroxyl group is disordered and has conformations ap with gamma = 171.1 (3)degrees [occupation of 61.4 (3)%] and sc with gamma = 52.4 (6)degrees [occupation of 38.6 (3)%]. The nucleobases are stacked in the crystal state.
