Synthesis, molecular structure, and chemical behavior of hydrogen trans-bis(dimethyl sulfoxide)tetrachlororuthenate(III) and mer-trichlorotris(dimethyl sulfoxide)ruthenium(III): The first fully characterized chloride-dimethyl sulfoxide-ruthenium(III) complexes

The synthesis, molecular structure and chemical behavior of two chloride-dimethyl sulfoxide-ruthenium(III) derivatives, namely [(DMSO)2H][trans-Ru(DMSO)2Cl4] (1) and mer-Ru(DMSO)3Cl3 (2), are reported. They represent the first examples of fully characterized halogen-dimethyl sulfoxide-ruthenium(III) complexes. Further relevance in their synthesis comes from the known antitumor properties of isostructural Ru(III) complexes with heterocyclic nitrogen ligands and of halogen-dimethyl sulfoxide-ruthenium(II) complexes as well. The crystal structures of 1 and 2 have been determined by three-dimensional X-ray analyses. Crystal data are as follows: [(DMSO)2H][trans-Ru(DMSO)2Cl4], monoclinic, space group P2/n, a = 9.273 (1) ?, b = 16.509 (3) ?, c = 14.023 (3) ?, β = 100.79 (2)°, Z = 4, R = 0.041; for mer-Ru(DMSO)3Cl3, monoclinic, space group P21/c, a = 10.105 (2) ?, b = 13.832 (3) ?, c = 11.115 (2) ?, β = 94.39 (2)°, Z = 4, R = 0.028. In 1 there are two crystallographically independent [Ru(DMSO)2Cl4]- anions lying on crystallographic 2-fold axes, passing through Ru and two trans Cl atoms, so that the other two Cl atoms and the two S-bonded DMSO molecules are also trans to each other. Cations are provided by protonated DMSO molecules, [Me2SO?H?OSMe2]+. In 2 the three chlorine atoms are in the mer configuration, and the two trans DMSO molecules arc S-bonded to Ru, while the third one is O-bonded. Both complexes are intermediates in the synthesis of cis-RuCl2(DMSO)4 from hydrated RuCl3. Cyclic voltammetric evidence shows that, in dimethyl sulfoxide and dichloromethane solution, 2 is in equilibrium with an isomer that very likely differs in the coordination mode of one DMSO (S- to O-bonded isomerization). The chemical behavior of 1 and 2 in aqueous solution has been studied at low pH (3(H2O)2(DMSO)]. A completely similar behavior is found in methanol.
