Abstract: The asymmetric unit of the title complex salt, (C₁₂H₁₁ClN₅)[RuCl₄(NO)(C₂H₆OS)]·H₂O, contains a 6-(2-chlorobenzylamino)purinium cation, a tetrachlorido(dimethyl sulfoxide)nitrosylruthenate(III) anion and one solvent water molecule. The Ru^III atom is octahedrally coordinated by four Cl atoms in the equatorial plane, and by a dimethyl sulfoxide O atom and a nitrosyl N atom in axial positions. The cation is an N3-protonated N7 tautomer. Intermolecular N-HN hydrogen bonds connect two cations into centrosymmetric dimers, with an NN distance of 2.821 (4) Å. The crystal structure also involves N-HO, N-HCl and O-HCl hydrogen bonds.
