Preparation, characterisation, molecular and crystal structure of the octaruthenium arene clusters [Ru8H4(CO)18(η6-arene)](arene = C6H6or C16H16)
摘要:
Two octaruthenium arene clusters, [Ru8H4(CO)(18)(eta(6)-arene)] (arene = C6H6 1 or C16H16 2), have been isolated from the thermolysis of [Ru-3(CO)(12)] in octane, in the presence of cyclohexene (C6H10) or [2.2] paracyclophane (C16H16), respectively. Both compounds 1 and 2 have been characterised in the solid state by single-crystal X-ray diffraction and their molecular and crystal structures determined. The reaction of 2 with CO resulted in conversion to the carbido cluster [Ru6C(CO)(14)(mu 3 eta(2):eta(2):eta(2)-C16H16)] and [Ru-3(CO)(12)] in quantitative amounts. Compound 1 did not react in the same way but yielded both [Ru4H4(CO)(12)] and [Ru4H2(CO)(13)].
