3-beta-D-ribofuranosyl-6,7-dihydro-9H-thiazolo[3,2-a]purin-9-one hydrate.
The title molecule, C12H14N4O5S.H2O (I), has a syn-XCN glycosyl torsion angle, which is stabilized by an intramolecular hydrogen bond between N3 of the tricylic base and O5' of the ribose (in a C2'-endo pucker). [The purine base, including atoms S and O6, of the molecule is planar to within 0.043 (2) A.] The tricyclic bases are stacked along a with an interplanar distance of 3.602 (3) A.
