title: The alpha-D anomer of 5-aza-7-deaza-2'-deoxyguanosine.
abstract: In the monohydrate of 2-amino-8-(2-deoxy-alpha-D-erythro-pentofuranosyl)-8H-imidazo[1,2-a][1,3,5]triazin-4-one, C(10)H(13)N(5)O(4) x H(2)O, denoted (I) or alpha Z(d), the conformation of the N-glycosylic bond is in the high-anti range [chi = 87.5 (3)]. The 2'-deoxyribofuranose moiety adopts a C2'-endo,C3'-exo((2')T(3')) sugar puckering (S-type sugar) and the conformation at the C4'-C5' bond is -sc (trans).
