Reaction of PbR2 [R = CH(SiMe3)2] with [Ru3-(CO)12] at 60°C afforded the first ruthenium-lead clusters [Ru3(μ-PbR2)(μ-CO)2(CO)9] (1) and [Ru3(μ- PbR2)2-(μ-CO)(CO)9] (2). After separation the compounds were characterized by 1H and 13C NMR and IR spectroscopies, FAB-MS, and, for 2, by a single-crystal X-ray study. The structure gives the first reported Ru-Pb bond lengths and shows the cluster to have a planar pentametallic array with two PbR2 and one CO bridging the three sides of an Ru3 triangle. A greatly improved yield for the preparation of PbR2 is also reported. Compound 2 crystallizes in the triclinic space group P1 with unit cell dimensions a = 12.279(6) A?, b = 15.406(6) A?, c = 20.775-(5) A? α = 99.54(6)°, β = 107.47(6)°, γ = 109.59(6)°, U = 3373.1(10) A?3, and Z = 2. A total of 10179 unique observations gave a merging R of 0.038 and a conventional R of 0.0756.
