Treatment of 1 equivalent of the reagent CR)(CO)2(η5-C2B9H9Me2)> (R = C6H4Me-4), in the presence of TlBF4, with 0.5 equivalent of the compounds > (n = 2-6) in CH2Cl2 affords the complexes (CO)4(η5C2B9H9Me2)2>.The crystal structure of the species with n = 4 has been determined by X-ray crystallography, confirming that the molecule has two RC<*>W(CO)2(η5-C2B9H9Me2) fragments bridged by an AuP(Ph)2CH2CH2CH2CH2(Ph)2PAu unit, with a centre of inversion at the midpoint of the chain of methylene groups.The W-Au bonds <2.798(1) Angstroem> are asymmetrically bridged by the p-tolylmethylidyne ligands .In a similar manner, the compounds 5-C2B9H9Me2)2> have been prepared from reactions between the gold compounds and the salt CR)(CO)2(η5-C2B9H9Me2)>.Addition of (cod = cycloocta-1,5-diene) to the complexes (CO)4(η5C2B9H9Me2)2> affords the chain cluster compounds 3-CR)2(μ-Ph2P(CH2)nPPh2>(CO)4(cod)2(η5-C2B9H9Me2)2>.The NMR data (1H, 13C-<1H>, 31P-<1H> and 11B-<1H> for the new complexes are reported and discussed.
