6-(2-Chloro-benzyl-amino)purinium tetra-chlorido(dimethyl sulfoxide-κO)(nitrosyl-κN)ruthenate(III) monohydrate.

ABSTRACT: The asymmetric unit of the title complex salt, (C(12)H(11)ClN(5))[RuCl(4)(NO)(C(2)H(6)OS)]·H(2)O, contains a 6-(2-chloro-benzyl-amino)purinium cation, a tetra-chlorido(dimethyl sulfoxide)nitro-sylruthenate(III) anion and one solvent water mol-ecule. The Ru(III) atom is octa-hedrally 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. Inter-molecular N-H⋯N hydrogen bonds connect two cations into centrosymmetric dimers, with an N⋯N distance of 2.821 (4) Å. The crystal structure also involves N-H⋯O, N-H⋯Cl and O-H⋯Cl hydrogen bonds.
