C6Me6RuCl2 (PR3) compounds (I, PR3 = PMe3; II, PR3 = PMePh2) react with AgPF6 in acetone via the intermediates PF6 (IV, V) to give the dinuclear complexes <(C6Me6RuPR3)2(μ-Cl)2>(PF6)2 (VII, VIII).When PF6 (VI) is treated with CH2Cl2, a mixture of products is formed containing the compounds 6-C6H5PPh2)>(PF6)2 (X) and <(C6Me6Ru)2(μ-Cl)3>PF6 (XI).The X-ray structural analysis of X shows a symmetrical arrangement of the ruthenium atom to both six-membered rings.The phosphorus atom of the η⁶-C6H5PPh2 ligand is somewhat bent towards the metal; there is, however, no difference in the Ru-C bond lengths (average value 223 pm) between the metal and the two aromatic ring systems.
