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.
标题配合物盐（C₁₂H₁₁ClN₅）[RuCl₄(NO)(C₂H₆OS)]·H₂O的不对称单元包含一个6-(2-氯苄基氨基)嘌呤阳离子、一个四氯（二甲亚砜）亚硝酰钌(III)阴离子和一个溶剂水分子。Ru(III)原子在赤道平面上由四个Cl原子八面体配位，在轴向位置由一个二甲亚砜O原子和一个亚硝酰N原子配位。阳离子是N3质子化的N7互变异构体。分子间N-H⋯N氢键将两个阳离子连接成中心对称二聚体，N⋯N距离为2.821 (4) Å。晶体结构还涉及N-H⋯O、N-H⋯Cl和O-H⋯Cl氢键。
