Abstract

The title synthetic analog of purine nucleosides, C16H16Cl2N4O7, has its acetyl-ated β-furan-ose ring in a 3'β-envelope conformation, with the corresponding C atom deviating by 0.602 (5) Å from the rest of the ring. The planar part of the furan-ose ring forms a dihedral angle of 65.0 (1)° with the mean plane of the purine bicycle. In the crystal, mol-ecules form a three-dimensional network through multiple C-H⋯O and C-H⋯N hydrogen bonds and C-H⋯π interactions.
