Treatment of [RuCl2(DMSO)4] with tripod [tripod = MeC(CH2EPh2)3, E = P (triphos) or As (triars)] yields [Ru2(μ-Cl)3-(tripod)2]Cl. In the case of triars the mononuclear intermediate [RuCl2(DMSO)(triars)] can be isolated. This condenses to the corresponding trichloro-bridged complex in MeOH. The chloride ligands of [Ru2(μ-Cl)3(tripod)2]Cl can be abstracted by AgCF3SO3 in MeCN to yield [Ru(MeCN)3(tripod)](CF3SO3)2. When the chloride abstraction is carried out in DMSO and above 100 °C, the products are [Ru(DMSO)3(tripod)](CF3SO3)2, whereas if the reaction is carried out below 100 °C, the mixed-solvent complexes [Ru(H2O)(DMSO)2(tripod)](CF3SO 3)2 are obtained. Reaction of the DMSO complexes with carbon monoxide gives the dicarbonyl triflate complexes [Ru(CF3SO3)(CO)2(tripod)](CF3SO 3). The X-ray diffraction study of a crystal of [Ru2(μ-Cl)3(tripod)2][BPh4] (orthorhombic, of space group Pccn and with a = 19.991 (8) A?, b = 18.388 (7) A?, c = 25.510 (10) A?, and Z = 4) is reported.
