Zusammenfassung: 
In the monohydrate of 2-amino-8-(2-deoxy-alpha-d-erythro-pentofuranosyl)-8H-imidazo[1,2-a][ 1,3,5]triazin-4-one, C10H13N5O4.H2O, denoted (I) or alphaZ(d), the conformation of the N-glycosylic bond is in the high-anti range [chi = 87.5 (3)degrees]. The 2'-deoxyribofuranose moiety adopts a C2'-endo,C3'-exo(T-2'(3')) sugar puckering (S-type sugar) and the conformation at the C4'-C5' bond is -sc (trans).
