The reaction of 2,3,5,6-tetra-2-pyridylpyrazine (tppz) with dichlorotetrakis(dimethyl sulfoxide)ruthenium(II) in dimethyl sulfoxide (DMSO) yielded the title centrosymmetric dinuclear complex, [Ru2Cl 4(C24H16N6)(C3H 6OS)2]·2C2H6OS·2H 2O or cis,cis-[{Ru(DMSO)Cl2}2(μ-tppz)] ·2Me2CO·2H2O. Each ruthenium ion is in a distorted octahedral coordination in which the chloro ligands are cis to each other and DMSO is coordinated through sulfur. The asymmetric unit contains half of two independent molecules.
