The title compound, C(11)H(6)ClN(5)O(4)S, crystallized with two independent mol-ecules in the asymmetric unit. The benzene ring makes dihedral angles of 66.46 (8) and 85.77 (9)° with the mean plane of the purine ring in the two mol-ecules. In the crystal, inter-molecular π-π stacking inter-actions [centroid-centroid distance = 3.8968 (12) Å], C-Cl⋯π inter-actions [Cl⋯centroid = 3.2505 (10) Å, C-Cl⋯centroid = 161.56 (18)°] and non-classical C-H⋯O and C-H⋯N hydrogen bonds link the molecules.
