The title complex, NaRuCl(4)(C(4)H(4)N(2))(C(2)H(6)OS)(2), is the sodium salt of monoanionic octa-hedral Ru(III)Cl(4)(pyrimidine)(DMSO) in which the sulfur-bound dimethyl sulfoxide (DMSO) and pyrimidine ligand are oriented trans to one another on the Ru(III) atom. The average of the four Ru-Cl bond lengths is 2.355 (15) Å, and the Ru-S and Ru-N bond lengths are 2.2853 (3) and 2.1165 (11) Å, respectively. The complex forms a chain, with a six-coordinate sodium ion bridging the ruthenium(III) units. The sodium cation is coordinated by cis-chloride ligands on ruthenium [Na-Cl = 2.9576 (7) and 2.6988 (7) Å], chloride and DMSO ligands from the ruthenium complexes related by inversion [Na-Cl and Na-O = 2.8888 (7) and 2.2623 (12) Å, respectively], a nitro-gen ligand from the pyrimidine of the tetrachlorido-ruthenium(III) complex related by the twofold rotation axis [Na-N = 2.5224 (14) Å] and an oxygen-bound DMSO [Na-O = 2.3165 (12) Å].
