| Abstract: | The new organometallic cluster (η2-μ4-CO)2(CO)13(η6-C6Me6) has been prepared by the thermolysis of Ru3(CO)12 with hexamethylbenzene in octane and characterised by a single crystal X-ray diffraction study. It is isostructural with the known cluster Ru6(η2-μ4-CO)2(CO)13(η6-C6H3Me3) and the metal core constitutnts the same tetrahedral Ru4 unit with two edge-bridging Ru atoms. The mesitylene derivative has been shown to undergo rearrangement to afford the octahedral carbido cluster Ru6C(CO)14(η6-C6H3Me3), but this conversion is not observed for the new hexamethylbenzene derivative. |
