cis,cis,cis-Di-chlorido-bis-(N(4),N(4)-di-methyl-pyridin-4-amine-κN(1))bis-(dimethyl sulfoxide-κS)ruthenium(II).

The structure of the title compound, [RuCl(2)(C(7)H(10)N(2))(2)(C(2)H(6)OS)(2)], has monoclinic (P2(1)/n) symmetry. The Ru-N distances of the coordination compound are influenced by the trans chloride or di-methyl-sulfoxide-κS ligands. The mol-ecular structure exhibits disorder for two of the terminal methyl groups of a dimethyl sulfoxide ligand.
