Reactions of triruthenium clusters with quinolines: X-ray structures of [Ru-3(mu-CO)(CO)(7){mu(3)-eta(2)-P(C6H5)CH2P(C6H5)(2))}{mu-eta(2)-C9H5(CH3)N}] and [Ru-3(CO)(10)(mu-H){mu-eta(2)-C9H6N}]

The reactions of [Ru-3(CO)(10)(mu-dppm)] 4 with quinolines afforded [Ru-3(m u-CO)(CO)(7){mu(3)-eta(2)-P(C6H5)CH2P(C6H5)(2))} {mu-eta(2)-C9H5(R)N}] (8, R = 4-Me; 9, R = H) as the major products along with small amounts of known compound [Ru-3(CO)(9){mu(3)-eta(3)-P(C6H5)CH2P(C6H5)(C6H4)}] 5. The molecu lar structure of 8 has been determined by single crystal X-ray studies. The reaction of 5 with 4-methylquinoline in refluxing cyclohexane afforded 8 a nd two known dinuclear compounds, [Ru-2(CO)(6){mu-CH2P(C6H5)(C6H4)P(C6H5}] 10 and [Ru-2(CO)(6){mu-(C6H4)P(C6H5)(CH2)P(C6H5}] 11, in 40, 12, and 10% yi elds, respectively. The compounds 10 and 11 are also formed from the thermo lysis of 4 in addition to the major compound 5. The solid state structure o f the previously reported [Ru-3(CO)(10)(eta-H){mu-eta(2)-C9H6N}] 2a is also reported for comparison.
