Description:
The trichloro-bridged dinuclear RuII complex tri-μ-chloro-bis{[1,1,1-tris(diphenylphosphinomethyl)ethane-κ3 P,P′,P′′]ruthenium(II)} hexafluorophosphate ethanol solvate, [Ru2Cl3(tripod)2]PF6·C2H6O, containing the tripod [1,1,1-tris(diphenylphosphinomethyl)ethane, C41H39P3] ligand, was unexpectedly obtained from the reaction of [RuIIICl3(tripod)] with 1,4-bis(diphenylphosphino)butane (dppb), followed by precipitation with NH4PF6. The magnetic moment of the compound at room temperature indicates that the dinuclear [Ru2(μ-Cl)3(tripod)2]+ cation is diamagnetic. A single-crystal X-ray structure determination revealed that the two Ru atoms are bridged by the three Cl atoms. The coordination sphere of each Ru atom is completed by the three P atoms of a tripod ligand. The two P3Ru units are exactly eclipsed, while the bridging Cl atoms are staggered with respect to the six P atoms. The Ru...Ru distance is 3.3997 (7) Å and the mean Cl—Ru—Cl bond angle is 77.7°.
