The title compound, C17H19N5O6S, crystallizes from a water-acetone solution. The adenine base is in an anti conformation, with a glycosyl torsion angle of - 166.5 (4)degrees. The ribose sugar adopts an envelope conformation (E-3). The toluenesulfonyl moiety is nearly perpendicular to the base. Both Watson-Crick and Hoogsteen sites, N1 and N6, and N6 and N7, of the adenine base are involved in a pair of hydrogen bonds, forming an A.A.A triplet pattern in the crystal lattice.
